Answer:
The Mach number is 2.866
Total temperature To = 528.524K
Explanation:
Temperature (T) = 200K
For air, r= 1.4
To find the Mach number we use:
1.6426 = 0.2M^2
M = 2.866
To find Total Temperature :
To =528.524K
The primary difference between integrated/concurrent engineering development and functional/sequential development is: Integrate

Answer:
A) 3783.952 kJ/kg
B) 34.5%
C) 2476.67 kJ/kg
Explanation:
A) Determine the rate of heat addition entering the first-stage turbine
Qin ( 1st stage ) = ( h1 - h6 ) + ( h3 - h2 )
= ( 3321.4 - 164.07 ) + ( 3438.566 - 2811.944 )
= 3783.952 kJ/kg
<em>h values are gotten from super heated table </em>
B) Determine the thermal efficiency
n = 34.5%

C) Rate of heat transfer from working fluid passing through the condenser to the cooling water
Qout = h4 - h5
= 2628.2 - 151.53
= 2476.67 kJ/kg
Answer:
Explanation:
Kelvin's climbing represents the <em>absolute temperature</em>. Temperature is a measure of the molecular kinetic energy of translation. If the molecules move quickly, with the same energy as in the walls of the container, which makes us feel like "heat". If the molecules do not move, the temperature is zero. 0 K.
The Celsius scale has an <em>artificial zero</em>, defined in the solidification temperature of the water. It is very useful to talk about the weather, and about some simpler technical matters. But it is artificial.
