Answers
To replace non-alphabetic and non-digit characters to space, we can use the `isalnum()` function. This function checks if a given character is an alphanumeric character or not. If it is not an alphanumeric character, we can replace it with a space character.
Here is the implementation of the function:
```cpp
#include
#include
using namespace std;
void replaceNonAlphanumeric(char s[], int size) {
for (int i = 0; i < size; i++) {
if (!isalnum(s[i])) {
s[i] = ' ';
}
}
}
int main() {
int size;
cin >> size;
char s[size];
for (int i = 0; i < size; i++) {
cin >> s[i];
}
replaceNonAlphanumeric(s, size);
cout << s;
return 0;
}
```
Sample Input:
```
9 123#$ABc
```
Sample Output:
```
123 ABc
```
The function `replaceNonAlphanumeric()` iterates through each character in the input array and checks if it is an alphanumeric character using the `isalnum()` function. If it is not an alphanumeric character, it replaces it with a space character. The function then prints the modified array.

what is the speed of a spur gear with 42 teeth driven by a pinion gear with 14 teeth turning 420 rpm?
Answers
The formula for calculating gear speed is: (rpm of the driving gear * number of teeth on the driving gear) / number of teeth on the driven gear.
What is the formula for calculating gear speed?To calculate the speed of the spur gear, we can use the gear ratio formula, which is gear ratio = number of teeth on driven gear (spur gear) / number of teeth on driving gear (pinion gear).
In this case, the gear ratio is 42/14 = 3.
Next, we can use the formula for gear speed, which is gear speed = pinion gear speed / gear ratio.
Since the pinion gear is turning at 420 rpm, the gear speed of the spur gear is:
gear speed = 420 rpm / 3 = 140 rpm.
Therefore, the speed of the spur gear with 42 teeth driven by a pinion gear with 14 teeth turning at 420 rpm is 140 rpm.

2-derive the outputs' boolean equations (written in simplified forms) for decimal
to bcd priority encoder such that the smallest digit has the highest priority. show
all the steps for the simplification.
Answers
To derive the output Boolean equations for a decimal to BCD (Binary-Coded Decimal) priority encoder, we need to follow a step-by-step process. Let's assume the inputs are D3, D2, D1, and D0, representing the decimal input digits from 0 to 9.
Step 1: Determine the number of outputs required.
In a decimal to BCD priority encoder, we need four outputs to represent the BCD code for each decimal input digit. Let's denote the outputs as Y3, Y2, Y1, and Y0.
Step 2: Write the truth table.
Construct a truth table with inputs (D3, D2, D1, D0) and outputs (Y3, Y2, Y1, Y0) for all possible input combinations. In this case, the truth table will have 10 rows (corresponding to the decimal digits 0 to 9).
Step 3: Determine the outputs based on priority.
The priority encoder assigns a unique code to each input, giving priority to the smallest input digit. The priority order for the decimal digits is as follows: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Based on this priority, we can determine the outputs (Y3, Y2, Y1, Y0) for each decimal input digit in the truth table.
Step 4: Write the Boolean equations for each output.
To simplify the Boolean equations, we can use Karnaugh maps (K-maps) when the number of inputs is small. In this case, we have four inputs (D3, D2, D1, D0), which are convenient for K-map simplification.
Construct a separate K-map for each output (Y3, Y2, Y1, Y0) and fill in the corresponding output values based on the truth table.
Step 5: Simplify the Boolean equations using K-maps.
Analyze each K-map and group adjacent 1s to form product terms. These product terms will represent the simplified Boolean equations for the outputs.
Step 6: Write the final simplified Boolean equations.
Based on the simplified product terms obtained from the K-maps, write the final Boolean equations for each output (Y3, Y2, Y1, Y0).
Following these steps will allow you to derive the outputs' Boolean equations in simplified form for a decimal to BCD priority encoder with the smallest digit having the highest priority.

A shell-and tube heat exchanger (two shells, four tube passes) is used to heat 10,000 kg/h of pressurized water from 35 to 120 oC with 5000 kg/h pressurized water entering the exchanger at 300 oC. If the overall heat transfer coefficient is 1500 W/m^2-K, determine the required heat exchanger area.
Answers
Answer:
4.75m^2
Explanation:
Given:-
- Temperature of hot fluid at inlet: \(T_h_i = 300\) °C
- Temperature of cold fluid at outlet: \(T_c_o = 120\) °C
- Temperature of cold fluid at inlet: \(T_c_i = 35\) °C
- The overall heat transfer coefficient: U = 1500 W / m^2 K
- The flow rate of cold fluid: m_c = 10,00 kg/ h
- The flow rate of hot fluid: m_h = 5,000 kg/h
Solution:-
- We will evaluate water properties at median temperatures of each fluid using table A-4.
Cold fluid: Tci = 35°C , Tco = 35°C
Tcm = 77.5 °C ≈ 350 K --- > \(C_p_c = 4195 \frac{J}{kg.K}\)
Hot fluid: Thi = 300°C , Tho = 150°C ( assumed )
Thm = 225 °C ≈ 500 K --- > \(C_p_h = 4660 \frac{J}{kg.K}\)
- We will use logarithmic - mean temperature rate equation as follows:
\(A_s = \frac{q}{U*dT_l_m}\)
Where,
A_s : The surface area of heat exchange
ΔT_lm: the logarithmic differential mean temperature
q: The rate of heat transfer
- Apply the energy balance on cold fluid as follows:
\(q = m_c * C_p_c * ( T_c_o - T_c_i )\\\\q = \frac{10,000}{3600} * 4195 * ( 120 - 35 )\\\\q = 9.905*10^5 W\)
- Similarly, apply the heat balance on hot fluid and evaluate the outlet temperature ( Tho ) :
\(T_h_o = T_h_i - \frac{q}{m_h * C_p_h} \\\\T_h_o = 300 - \frac{9.905*10^5}{\frac{5000}{3600} * 4660} \\\\T_h_o = 147 C\)
- We will use the experimental results of counter flow ( unmixed - unmixed ) plotted as figure ( Fig . 11.11 ) of the " The fundamentals to heat transfer" and determine the value of ( P , R , F ).
- So the relations from the figure 11.11 are:
\(P = \frac{T_c_o - T_c_i}{T_h_i - T_c_i} \\\\P = \frac{120 - 35}{300 - 35} \\\\P = 0.32\)
\(R = \frac{T_h_i - T_h_o}{T_c_o - T_c_i} \\\\R = \frac{300 - 147}{120 - 35} \\\\R = 1.8\)
Therefore, P = 0.32 , R = 1.8 ---- > F ≈ 0.97
- The log-mean temperature ( ΔT_lm - cf ) for counter-flow heat exchange can be determined from the relation:
\(dT_l_m = \frac{( T_h_i - T_c_o ) - ( T_h_o - T_c_i ) }{Ln ( \frac{( T_h_i - T_c_o )}{( T_h_o - T_c_i )} ) } \\\\dT_l_m = \frac{( 300 - 120 ) - ( 147 - 35 ) }{Ln ( \frac{( 300-120 )}{( 147-35)} ) } \\\\dT_l_m = 143.3 K\)
- The log - mean differential temperature for counter flow is multiplied by the factor of ( F ) to get the standardized value of log - mean differential temperature:
\(dT_l = F*dT_l_m = 0.97*143.3 = 139 K\)
- The required heat exchange area ( A_s ) can now be calculated:
\(A_s = \frac{9.905*10^5 }{1500*139} \\\\A_s = 4.75 m^2\)

Answers
For moving muons in the given scenario, the values of β, K, and p are 0.824, (pc² / 104.977 MeV/c²), and √[(K + m0c²)²/c⁴ - m0²c²/c⁴] / c, respectively. These values are obtained through calculations using the provided data and relevant formulas.
The mass of a muon is 207 times the electron mass; the average lifetime of muons at rest is 2.20 μs. In a certain experiment, muons moving through a laboratory are measured to have an average lifetime of 6.85 μs.
The rest energy of the electron is 0.511 MeV. Formulas:Total energy of the particle: E = (m²c⁴ + p²c²)¹/², Where,
E = Total energy of the particle m = Rest mass of the particlec = Speed of light in vacuum p = Momentum of the particleβ = v/c, Where, β = Velocity of the particle/cK = Total Kinetic Energy of the particleK = E - mc²p = Momentum of the particle p = mvTo calculate the value of β for moving muons, we need to calculate the velocity of the muons. To calculate the velocity of the muons, we can use the concept of the lifetime of the muons. The average lifetime of muons at rest is 2.20 μs.
The moving muons have an average lifetime of 6.85 μs. The time dilation formula is given byt = t0 / (1 - β²)c², where,
t = Time interval between the decay of the muon measured in the laboratory.t0 = Proper time interval between the decay of the muon as measured in the muon's rest frame.c = Speed of light in vacuumβ = Velocity of the muon.Hence,t0 = t / (1 - β²)c²t0 = 2.20 μs / (1 - β²)c²t = 6.85 μs. From these two equations, we can calculate the value of β.6.85 μs / t0 = 6.85 μs / (2.20 μs / (1 - β²)c²)β² = 1 - (2.20 μs / 6.85 μs)β² = 0.679β = 0.824. Hence, the value of β is 0.824.
To calculate the value of K for moving muons, we need to calculate the total energy of the muons. The rest mass of the muon is given bym0 = 207 × 0.511 MeV/c²m0 = 104.977 MeV/c².
The total energy of the muon is given byE = (m²c⁴ + p²c²)¹/²E = (104.977 MeV/c²)²c⁴ + (pc)²K = E - m0c²K = [(104.977 MeV/c²)²c⁴ + (pc)²] - (104.977 MeV/c²)c²K = pc² / (104.977 MeV/c²). Hence, the value of K for moving muons is pc² / (104.977 MeV/c²).
To calculate the value of p for moving muons, we can use the value of K calculated in p = √(E²/c⁴ - m0²c²/c²) / cHere,E = (m²c⁴ + p²c²)¹/²E²/c⁴ = m²c⁴/c⁴ + p²p²c²/c⁴ = (K + m0c²)²/c⁴p = √[(K + m0c²)²/c⁴ - m0²c²/c⁴] / c. Hence, the value of p for moving muons is √[(K + m0c²)²/c⁴ - m0²c²/c⁴] / c.
Therefore, the values of β, K, and p are 0.824, (pc² / 104.977 MeV/c²), and √[(K + m0c²)²/c⁴ - m0²c²/c⁴] / c respectively.

1) The maximum bending stress in the beam occurs on the cross section that carries the largest
\($\sigma_{\max }=\frac{|M|_{\max } c}{I}=\frac{\left(16 \times 10^{3}\right)(0.1)}{80.0 \times 10^{-6}}=20.0 \times 10^{6} \mathrm{~Pa}=20.0 \mathrm{MPa}$$\)
What is the bending stress formula?The bending stress is computed for the rail by the equation Sb = Mc/I, where Sb is the bending stress in pounds per square inch, M is the maximum bending moment in pound-inches, I is the moment of inertia of the rail in (inches)4, and c is the distance in inches from the base of rail to its neutral axis.
2) The stress distribution on the cross section at D is shown in Fig. (d). When drawing the figure, we were guided by the following observations: (i) the bending stress varies linearly with distance from the neutral axis; (ii) because M_{max} is positive, the top half of the cross section is in compression and the bottom half is in tension; and (iii) due to symmetry of the cross section about the neutral axis, the maximum tensile and compressive stresses are equal in magnitude.
3) the bending stress at a point on section B that is 35 mm below the top of the beam.

In a wheatstone bridge three out of four resistors have of 1K ohm each ,and the fourth resistor equals 1010 ohm. If the battery voltage is 100V,what is the approximate value of the open circuit voltage ? If the output of the bridge is connected to a 4 K ohm resistor, how much current would flow through the resistor?
Answers
Answer:
248.756 mV
49.7265 µA
Explanation:
The Thevenin equivalent source at one terminal of the bridge is ...
voltage: (100 V)(1000/(1000 +1000) = 50 V
impedance: 1000 || 1000 = (1000)(1000)/(1000 +1000) = 500 Ω
The Thevenin equivalent source at the other terminal of the bridge is ...
voltage = (100 V)(1010/(1000 +1010) = 100(101/201) ≈ 50 50/201 V
impedance: 1000 || 1010 = (1000)(1010)/(1000 +1010) = 502 98/201 Ω
__
The open-circuit voltage is the difference between these terminal voltages:
(50 50/201) -(50) = 50/201 V ≈ 0.248756 V . . . . open-circuit voltage
__
The current that would flow is given by the open-circuit voltage divided by the sum of the source resistance and the load resistance:
(50/201 V)/(500 +502 98/201 +4000) = 1/20110 A ≈ 49.7265 µA

To maintain a constant pressure in the evaporator when the system is running, an axv ____ refrigerant flow when the evaporator pressure drops.
Answers
**To maintain a constant pressure in the evaporator when the system is running, an expansion valve (axv) increases refrigerant flow when the evaporator pressure drops.**
The expansion valve is a crucial component in a refrigeration system that regulates the flow of refrigerant into the evaporator. Its primary function is to reduce the pressure and temperature of the refrigerant as it enters the evaporator.
When the evaporator pressure drops, it indicates that the cooling load has increased, and more refrigerant is required to maintain the desired cooling effect. In response, the expansion valve adjusts its opening, allowing a greater flow of refrigerant into the evaporator. This increased flow helps to maintain a constant pressure within the evaporator and ensures efficient heat transfer between the refrigerant and the surrounding air or fluid.
By modulating the refrigerant flow in accordance with the evaporator pressure, the expansion valve plays a crucial role in maintaining the proper operation and performance of the refrigeration system.
