Problem 6.25:

A flow process utilizes steam as the working fluid. The steam, initially at 30 bar and 700
°C (state A), is cooled under constant pressure to a temperature of 380 °C (state B) and it subsequently expands adiabatically to a final pressure of 1 bar (state C) through a turbine whose efficiency is 75%.

a) Plot the path of a Mollier diagram.

b) Determine the energy balances.

Problem 6.26:

A flow process that operates with steam has one inlet stream (A) and two outlet streams (B and C). Stream A is at 20 bar, 25 °C, and has a mass flow rate of 10 kg/s; stream B is saturated liquid at 20 bar and has a flow rate of 7 kg/s; stream C is at 20 bar. The process receives heat at the rate of 14,100 kW from a heat source at 25 °C.

a) What is the temperature of stream C?

b) Determine the entropy generation.
