Answer:
Recall the Entropy Balance (Second Law of Thermodynamics) equations for the system below
And for ideal gas, we know that
Change in Entropy of the air kJ/Kg.K, ΔS = S₁ - S
₂ = Cp Ln (T₂/T₁) - R Ln(P₂/P₁)
where R is gas constant =0.287kJ/kg.K and given
Cp=1.015 kJ/ kg.K
T₂ = 465k T₁=270k, P1=58kPa, P2=350kPa
substituting these values into the eqn above, we have
S = (1.015x 0.544) - (0.287x1.798)
S = 0.0363kJ/Kg.K
Hence, the mass specific entropy change associated with the compression process = 0.0363kJ/Kg.K

Answer:
Sampling rate = 90
23 and 45 Hz
Explanation:
The Nyquist criteria states that the sampling frequency must be at least twice of the highest frequency component.
(a) We have 10, 12, 13, 23, and 45 Hz signals
The highest frequency component in this list is 45 Hz
So minimum sampling frequency needed to avoid aliasing would be
Sampling rate = 2*45 = 90 sps
Hence a sampling rate of 90 samples per second would be required to avoid aliasing.
(b) if a sampling rate of 40 sps is used then
40 = 2*f
f = 40/2 = 20 Hz
Hence 23 and 45 Hz components will be aliased.
Answer:
53 sec / cycle
Explanation:
Displayed red time = 35 seconds
Start up lost time = 2 seconds
Yellow time = 4 seconds
Red time = 1 second
Total lost time L = 2n + r
L = lost time
n = number of phase
R = red time
35+2+4+4*1
= 45
L = 2x4+45
= 53 sec/cycle
The total lost time is typically calculated as 53 seconds per cycle
