Final answer:
The compressor efficiency (nc) of an adiabatic compressor operating at steady state is 0, so the correct answer is d) 1.0. Therefore the correct answer is d) 1.0.
Step-by-step explanation:
The compressor efficiency (nc) of an adiabatic compressor operating at steady state can be calculated using the formula nc = (Hs - Hr) / Hs, where Hs is the enthalpy change of the gas in the compressor and Hr is the reversible enthalpy change of the gas.
Since the compressor is adiabatic, there is no heat transfer (Q) into or out of the system, and as a result, the reversible enthalpy change is equal to the actual enthalpy change (Hr = Hs).
Therefore, the compressor efficiency (nc) is given by nc = (Hs - Hr) / Hs = (Hs - Hs) / Hs = 0 / Hs = 0.
Since the compressor efficiency is 0, the correct answer is d) 1.0.
A compressor is a mechanical device used to increase the pressure of a gas by reducing its volume. It's widely used in various applications and industries where pressurized gas is needed for power, refrigeration, air conditioning, and other purposes.
