Problem 2: Water Vaporization in an adiabatic unit

An adiabatic vessel has a valve that allows some water to be released. Initially it has 500 Kg of saturated liquid water

at a temperature of 50°C. Find the following:

A. The temperature of remaining water if 10 Kg of water vapor escapes through the valve.

B. If the remaining water is at 20°C, find the amount of water escaped as vapor.
