The conditions in problem 4 represent the best possible situation, when there is no friction etc. in the system. Real compressors do not operate reversibly and will require more work than you calculated. (The compressor is still adiabatic.) Assume you tested the compressor and measured the following exit conditions.
a) Calculate the actual work per kg required to run the compressor
b) Calculate the isentropic efficiency.

#2. (30 pts) A turbocharger boosts the inlet air pressure to an automobile engine. It consists of an exhaust gas-driven turbine directly connected to an air compressor, as shown in a below figure. For a certain engine load, the conditions are given in the below figure. Assume that both the turbine and the compressor are reversible and adiabatic, having also the same mass flow rate. Engine power...

Problem 4 – Entropy transfer in a control volume (18 pts) An
adiabatic reversible steam turbine steadily processes 2 kg/s of
steam at 5 MPa and 450°C, which is exhausted at 100 kPa and 100°C.
The turbine exhibits an isentropic efficiency of 0.85. a) Draw a
schematic representation of the system with all the energy
interactions involved. (2pts) b) Determine the h (kJ/kg) and s

a) Company A designed a heat pump to
supply heat into a library in Canada during
winter, so that the library can maintain to be at 20°C. The heat
pump utilizes
12,000 L/min of Refrigerant-134a as the working fluid and absorb
heat from an
industrial water stream. The water stream enters the evaporator at
50°C and exits
at 25°C. The refrigerant enters the evaporator at 10°C with 90%
moisture content
and leaves at 20°C. There is no pressure drop in...
