Answer:
The required mechanical work is required to reduce each day by 1.05×10^8 Joules.
Explanation:
Coefficient of Performance (COP) = Q/W
Q is thermal energy absorbed by the air conditioner
W is mechanical work done
Q = 3.9×10^8 J
COP of old air conditioner = 2.3
W = Q/COP = 3.9×10^8/2.3 = 1.70×10^8 J
COP of new air conditioner = 6
W = Q/COP = 3.9×10^8/6 = 6.5×10^7 J
Reduction in mechanical work = (1.7×10^8) - (6.5×10^7) = 1.05×10^8 J
Answer:

Explanation:
The turbine at steady-state is modelled after the First Law of Thermodynamics:

The specific enthalpies at inlet and outlet are, respectively:
Inlet (Superheated Steam)

Outlet (Liquid-Vapor Mixture)

The power produced by the turbine is:



Answer:
parentheses
Explanation:
print 100/4
SyntaxError: Missing parentheses in call to 'print'.
print (100/4)
25.0
You need parentheses with print statements in python.
Hope this helps!
