Question

A well-insulated rigid tank contains 3 kg of a satu-
rated liquid–vapor mixture of water at 200 kPa. Initially, three-
quarters of the mass is in the liquid phase. An electric resistance
heater placed in the tank is now turned on and kept on until
all the liquid in the tank is vaporized. Determine the entropy
change of the steam during this process.

Answer 1

Answer:

Step 1 of 3

Obtain the specific entropy of the saturated water at from the table A-5.
