A concrete column has a diameter of 390 mm and a length of 2.8 m . If the density (mass/volume) of concrete is 2.45 Mg/m3, determine the weight of the column in pounds.

Answers

Answer:  1804.61 lbs

Explanation:

Given, diameter of concrete column = 390 mm

= 0.390 m  [ 1 mm =0.001 m]

Radius = \(\dfrac{0.390}{2}=0.195\ m\)

also, Length = 2.8 m

Volume of column  (cylindrical)= \(\pi r^2l\)

\(=(3.14)(0.195)^2(2.8)\)

\(=0.3343158\ m^3\)

Density  \(=\dfrac{Mass }{Volume}=2.45\ Mg/m^3\)  

⇒ Mass = 2.45 x (Volume)

= 2.45 (0.3343158) Mg

= 0.81907371 Mg

⇒ Mass = 819.07271 kg  [1 Mg =1000 kg]

Weight = \({mass}\times{gravity}={819.07271}\times{9.8}=8026.91\ N\)

1 N= 0.22482 lb

Then, Weight = \(0.22482\times 8026.91=1804.61\ lb\)

Weight of the column in pounds.= 1804.61 lbs (approx)

Weight of the column is 1804.61 lbs.

Given that,

Diameter of column is 390mm or 0.39m.Length (l) of column is 2.8m.Density of column is 2.45 Mg/m3

According to the given data, calculation are as follows,

Diameter = 0.39m

So, radius (r) = 0.39 \(\div\) 2 = 0.195m

Volume of column = \(\pi r^{2}l \)

By putting the value, we get

Volume = [ (3.14)\(\times\) \((0.195)^{2} \) \(\times\) 2.8m ]

= \(0.3343158m^{3} \)

Now, as we know that,

Density = Mass \(\div\) Volume

Or, Mass (M) = Density \(\times\) Volume

= 2.45 \(\times\) 0.3343158

= 819.07271 kg

Now Weight = (M \(\times\) Gravity )         Value of gravity is 9.8.

Weight = 819.07271 kg \(\times\) 9.8

= 8026.91N

Where, 1N = 0.22482 lbs

So, Weight of the column = 1804.61 lbs

The base width is 11.0 m, and the side batters are 1V:2.5H. The canal lining comprises several layers with the top layer made up of compacted 300mm stones to protect the underlying layers from erosion. Operating depths range from 5.3m to 6.0 m. The average Manning’s n coefficient for this surface is 0.0325.

(iv) Operating procedures for the canal limit the rate of change of water level in the canal to prevent excessive negative water pressure on the canal lining. Briefly explain how this can be monitored to prevent damage to the impervious lining layer.

Answers

This can be monitored by installing a pressure transducer at an appropriate location along the canal. The transducer can send signals to a control room, where the water level changes can be monitored. If the water level changes too quickly, the flow rate can be adjusted to prevent damage to the impervious lining layer.

Explanation of what would happen if a 50 mm diameter stone size was used for the lining surfaceIf a 50 mm diameter stone size was used for the lining surface instead of the existing 300 mm size, the voids between the stones would be much larger. This would allow the underlying layers to be exposed to erosion, leading to damage and potential failure of the lining. Therefore, using smaller stone sizes would not be recommended.(iv) Brief explanation of how monitoring can prevent damage to the impervious lining layerTo prevent excessive negative water pressure on the canal lining, the rate of change of water level in the canal must be limited.

Consider the following method, which is intended to return the sum of all the even digits in its parameter num. For example, sumEvens(15555234) should return 6, the sum of 2 and 4.
/** Precondition: num >= 0 */
public static int sumEvens(int num)
{
if (num < 10 && num % 2 == 0)
{
return num;
}
else if (num < 10)
{
return 0;
}
else if (num >= 10 && num % 2 == 0)
{
/* missing statement */
}
else
{
return sumEvens(num / 10);
}
}
Which of the following can be used as a replacement for /* missing statement */ so that the sumEvens method works as intended?
A. return sumEvens(num % 10);
B. return sumEvens(num / 10);
C. return num % 10 + sumEvens(num % 10);
D. return num % 10 + sumEvens(num / 10);
E. return num / 10 + sumEvens(num % 10);

Answers

The given method, sumEvens(num), aims to find the sum of all even digits in the given parameter num.

The method first checks if the num is a single-digit even number, in which case it returns the num. If num is a single-digit odd number, it returns 0. If num has more than one digit, it checks if the rightmost digit is even. If so, it needs to add that even digit to the sum of even digits in the remaining digits of num. For this purpose, it calls the same method recursively on the remaining digits of num. If the rightmost digit is odd, it simply removes that digit and calls the same method recursively on the remaining digits of num.

To achieve the desired functionality, we need to fill in the missing statement in the third if-else block.

Option A: return sumEvens(num % 10);
This option would return the sum of even digits in the rightmost digit of num. However, it does not take into account the remaining digits of num. Hence, this option is incorrect.

Option B: return sumEvens(num / 10);
This option would call the method recursively on the remaining digits of num, without considering the rightmost digit. Therefore, this option is also incorrect.

Option C: return num % 10 + sumEvens(num % 10);
This option correctly adds the rightmost even digit to the sum of even digits in the remaining digits of num. Hence, this option is correct.

Option D: return num % 10 + sumEvens(num / 10);
This option would add the rightmost even digit to the sum of even digits in the remaining digits of num, but it does not remove the rightmost digit from num before calling the method recursively. Hence, this option is incorrect.

Option E: return num / 10 + sumEvens(num % 10);
This option would not correctly add the even digits of num. Hence, this option is incorrect.

Therefore, the correct option to replace the missing statement is C. The final version of the method is as follows:
```
public static int sumEvens(int num)
{
   if (num < 10 && num % 2 == 0)
   {
       return num;
   }
   else if (num < 10)
   {
       return 0;
   }
   else if (num >= 10 && num % 2 == 0)
   {
       return num % 10 + sumEvens(num / 10);
   }
   else
   {
       return sumEvens(num / 10);
   }
}
```

Explanation:

Given that

Number of poles= 8

I.E.C. 180L motor frame

From data book , for 8 poles motor at 50 Hz

Speed = 730 rpm

Power factor = 0.75

Efficiency at 100 % load= 89.3 %

Efficiency at 50 % load= 89.1 %

Output power = 11 kW

Therefore the rated output power of 8 poles motor will be 11 kW. Thus the answer will be 11 kW.

P=11 kW

A germanium diode carries a current of 1 mA at room temperature when a forward bias of 0.15v is applied. Estimate the reverse saturation current at room temperature.

Answers

The reverse saturation current, denoted as I0, can be estimated using the diode equation:

I = I0 * (exp(qV/kT) - 1)

where I is the current through the diode, q is the charge of an electron, V is the voltage across the diode, k is Boltzmann's constant, and T is the temperature in Kelvin.

At room temperature, T = 298 K. We are given that the diode carries a current of 1 mA when a forward bias of 0.15 V is applied. Let's assume that the diode is ideal, meaning that it has no series resistance, so the voltage across the diode equals the forward bias voltage.

Plugging in these values, we get:

1E-3 A = I0 * (exp((1.602E-19 C)(0.15 V) / (1.381E-23 J/K)(298 K)) - 1)

Simplifying, we get:

1E-3 A = I0 * (exp(0.01275) - 1)

1E-3 A / (exp(0.01275) - 1) = I0

I0 = 2.34E-12 A, or approximately 0.23 nA. Therefore, the estimated reverse saturation current at room temperature is 0.23 nA.

Water at 158C is to be heated to 658C by passing it over a bundle of 4-m-long, 1-cm-diameter resistance heater rods maintained at 908C. Water approaches the heater rod bundle in normal direction at a mean velocity of 0.8 m/s. The rods are arranged in-line with longitudinal and transverse pitches of SL 5 4 cm and ST 5 3 cm. Determine the number of tube rows NL in the flow direction needed to achieve the indicated temperature rise.

Answers

The number of tube rows NL required to achieve a temperature rise from 158C to 658C of water passing over a bundle of resistance heater rods is 44, given a mean velocity of 0.8 m/s and longitudinal and transverse pitches of 4 cm and 3 cm, respectively.


Given these parameters, the temperature rise ΔT required is:
ΔT = Desired water temperature - Initial water temperature
ΔT = 65°C - 15°C
ΔT = 50°C
To achieve this temperature rise, we can use the LMTD (Log Mean Temperature Difference) method to find the heat transfer between the water and the heater rods. LMTD = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2)
Where ΔT1 is the temperature difference between the heater rod temperature and the initial water temperature, and ΔT2 is the temperature difference between the heater rod temperature and the desired water temperature:
ΔT1 = 90°C - 15°C = 75°C
ΔT2 = 90°C - 65°C = 25°C
LMTD = (75°C - 25°C) / ln(75°C / 25°C)
LMTD ≈ 43.95°C Now, we can use the following formula to calculate the number of tube rows needed:
NL = (Heat load) / (Heat transfer coefficient * Heat transfer area * LMTD)
Since we do not have the heat load or heat transfer coefficient values, it is not possible to determine the exact number of tube rows NL required to achieve the indicated temperature rise. Additional information on the heat load and heat transfer coefficient is necessary to provide an accurate answer.
