Assume all the processes to be reversible and the heat losses from the pump and the turbine to be negligible. (a) If steam enters a pump (operates between the pressure limits of 5 MPa and 10 kPa) as saturated liquid, determine the pump work (consumed) per unit mass. (b) If steam leaves a turbine (operates between the pressure limits of 5 MPa and 10 kPa) as saturated vapor, determine the turbine work (delivered) per unit mass.

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.
