Problem 6.9:

Steam enters a cooling tower at 200 °C and exits at 60 °C. Cooling is supplied by the surroundings which are assumed to be at 30 °C. The process takes place under atmospheric pressure (1 bar).

a) Calculate the amount of heat removed from the steam.

b) Calculate the entropy change of the steam.

c) What is the entropy generation?

d) Draw a PV graph and show the path of this process.

Problem 6.10:

Stream 1 enters a tank carrying steam at 5 bar, 300 °C at the rate of 1 kg/s. The stream is cooled by adiabatic mixing with water at 5 bar, 40 °C (stream 2). If the resulting stream is a vapor-liquid mixture with quality 18%, calculate the mass flow rate of stream 2, the entropy generation, and the lost work.
