Problem 50HP

It may be assumed that the expansion is reversible and adiabatic. What was the initial pressure in the cylinder, and how much work is done by the water?

ANSWER:

Solution 50HP

Step 1 of 3:

We are going to find the initial pressure of water and the work done by the water. The process is assumed to be reversible and adiabatic.

The initial temperature T1 = 300°C

The mass m = 1 kg

The final pressure P2 = 100 kPa

The final quality x2 = 90.2 % = 0.902
