19.11 The atmosphere is stable with a lapse rate of –0.2 °C/100 m. The surface air temperature is 15 °C. A parcel of air is released at the ground with a temperature of 25 °C. Calculate the maximum mixing height, in m.
Answer:
The maximum mixing height in meters is 5,000 m
Explanation:
In this question, we are expected to calculate the maximum mixing height in meters.
We identify the following parameters;
Lapse rate(L) = 0.2 °C/100 m = 0.002 °C/m (divide 0.2 by 100 to get this)
Mathematically;
Lapse rate(L) = Temperature difference/altitude (h)
Where the temperature difference is (25 °C -15 °C) = 10°C
Substituting this in the formula, we have;
0.002 = 10/h
h * 0.002 = 10
h = 10/0.002
Altitude(h) = 5,000 m

If the length of a chromosome is 10 and a schema H has three * symbols, what is the longest Defining Length possible? Your answer can only consist of digits (and if a real number, then also decimal point) and no other characters, punctuation, letters or spaces.
The longest defining length possible for the given schema is 8.
The longest defining length possible for a schema can be calculated based on the number of * symbols it contains and the length of the chromosome. In this case, the chromosome length is 10 and the schema H has three * symbols.
To calculate the longest defining length, we need to determine the number of possible values for each position in the schema where a * symbol is present. Since each position can take on either 0 or 1, the number of possible values for each position is 2.
Therefore, the longest defining length is calculated by raising 2 to the power of the number of * symbols in the schema. In this case, it would be 2 raised to the power of 3, resulting in 8.

min 4x1 - 3 x2
subject to
3x1 - x2 ≤ 6
5x1 - 4x2 ≥ 8
x1 - 6x2 =5
x1, x2 ≥ 0
The dual problem of a linear programming problem can be found by flipping the inequality signs and re-assigning the objective function as a constraint.
Given the following linear programming problem min 4x1 - 3 x2 subject to 3x1 - x2 ≤ 6 5x1 - 4x2 ≥ 8 x1 - 6x2 =5 x1, x2 ≥ 0To find the dual of the problem, the following steps can be taken:
Step 1: Flip the problem The first step in finding the dual problem is to flip the inequality signs of the constraint of the original problem. The constraints of the original problem are as follows:3x1 - x2 ≤ 65x1 - 4x2 ≥ 8x1 - 6x2 = 5Flipping the inequality signs of the above equations results in the following:3x1 - x2 ≥ 65x1 - 4x2 ≤ 8x1 - 6x2 = 5
Step 2: Re-assign the objective The next step is to re-assign the objective function of the original problem as a constraint. That is, the coefficients of the original objective function are used as constraints in the dual problem. Thus, for the given problem,
we have:4x1 - 3x2 = x0Step 3: Formulate the dual problem The dual problem can now be formulated by using the re-assigned objective function and the flipped inequality signs of the original problem. The coefficients of the original problem form the new objective function of the dual problem, while the flipped inequalities form the constraints of the dual problem. Therefore, the dual problem of the given problem is: minimize 6y1 + 8y2 + 5y3, subject to:3y1 + 5y2 + y3 ≥ 4- y1 - 4y2 - 6y3 ≥ -3Where y1, y2 and y3 are the dual variables corresponding to the original constraints.

An aircraft is turning at constant altitude, the turn following the arc of a circle of radius 1.5km. If the maximum allowable acceleration of the aircraft is 2.5 g, determine the maximum speed of the turn in km/hr
Take 9.8m/s²
The maximum speed of the turn is 279 km/hr.
How did we get the value?The maximum allowable acceleration of the aircraft is 2.5g, where g is the acceleration due to gravity, g = 9.8 m/s². Therefore, the maximum allowable centripetal acceleration can be calculated as:
a_max = 2.5g = 2.5 × 9.8 = 24.5 m/s²
In a circular motion, the centripetal acceleration is given by:
a_c = v² / r
where v is the speed of the aircraft and r is the radius of the circle. Rearranging this equation gives:
v = √(a_c × r)
Substituting the values given in the problem, we get:
v = √(a_max × r) = √(24.5 × 1500) = 77.5 m/s
Finally, we convert the speed from m/s to km/hr:
77.5 m/s × (60 × 60) / 1000 = 279 km/hr (rounded to the nearest whole number)
Therefore, the maximum speed of the turn is 279 km/hr.

The boost converter of Fig. 6-8 has parameter Vs 20 V, D 0.6, R 12.5 , L 10 H, C 40 F, and the switching frequency is 200 kHz. (a) Determine the output voltage. (b) Determine the average, maximum, and minimum inductor currents. (c) Determine the output voltage ripple. (d) Determine the average current in the diode. Assume ideal components.
Answer:
a) the output voltage is 50 V
b)
- the average inductor current is 10 A
- the maximum inductor current is 13 A
- the maximum inductor current is 7 A
c) the output voltage ripple is 0.006 or 0.6%V₀
d) the average current in the diode under ideal components is 4 A
Explanation:
Given the data in the question;
a) the output voltage
V₀ = V\(_s\)/( 1 - D )
given that; V\(_s\) = 20 V, D = 0.6
we substitute
V₀ = 20 / ( 1 - 0.6 )
V₀ = 20 / 0.4
V₀ = 50 V
Therefore, the output voltage is 50 V
b)
- the average inductor current
\(I_L\) = V\(_s\) / ( 1 - D )²R
given that R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6
we substitute
\(I_L\) = 20 / (( 1 - 0.6 )² × 12.5)
\(I_L\) = 20 / (( 0.4)² × 12.5)
\(I_L\) = 20 / ( 0.16 × 12.5 )
\(I_L\) = 20 / 2
\(I_L\) = 10 A
Therefore, the average inductor current is 10 A
- the maximum inductor current
\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] + [ V
given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz
we substitute
\(I_{Lmax\) = [20 / (( 1 - 0.6 )² × 12.5)] + [ (20 × 0.6 × 5) / (2 × 10) ]
\(I_{Lmax\) = [20 / 2 ] + [ 60 / 20 ]
\(I_{Lmax\) = 10 + 3
\(I_{Lmax\) = 13 A
Therefore, the maximum inductor current is 13 A
- The minimum inductor current
\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] - [ V
given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz
we substitute
\(I_{Lmin\) = [20 / (( 1 - 0.6 )² × 12.5)] - [ (20 × 0.6 × 5) / (2 × 10) ]
\(I_{Lmin\) = [20 / 2 ] -[ 60 / 20 ]
\(I_{Lmin\) = 10 - 3
\(I_{Lmin\) = 7 A
Therefore, the maximum inductor current is 7 A
c) the output voltage ripple
ΔV₀/V₀ = D/RCf
given that; R = 12.5 Ω, C = 40 μF = 40 × 10⁻⁶ F, D = 0.6, f = 200 Khz = 2 × 10⁵ Hz
we substitute
ΔV₀/V₀ = 0.6 / (12.5 × (40 × 10⁻⁶) × (2 × 10⁵) )
ΔV₀/V₀ = 0.6 / 100
ΔV₀/V₀ = 0.006 or 0.6%V₀
Therefore, the output voltage ripple is 0.006 or 0.6%V₀
d) the average current in the diode under ideal components;
under ideal components; diode current = output current
hence the diode current will be;
\(I_D\) = V₀/R
as V₀ = 50 V and R = 12.5 Ω
we substitute
\(I_D\) = 50 / 12.5
\(I_D\) = 4 A
Therefore, the average current in the diode under ideal components is 4 A
