3)For a given TC and TH, the vapor compression cycle has a higher COP than the Carnot cycle.
Group of answer choices
Answer 1:
Isentropic means the turbine works in reversible isentropic process and according to law of thermodynamics, no process is efficient than reversible process.
Write the expression for the relation between the isentropic turbine work produced and real turbine work produced.
The efficiency of the real turbine always less than 100% or 1 so the real work output will be less than the isentropic work done by the turbine.
Hence, statement 1 is True.
