Problem 107P
A closed tank is partially filled with water at 80°C. If the air above the water is completely evacuated, determine the absolute pressure in the evacuated space. Assume the temperature to remain constant.
ANSWER:
Solution 107P
Step 1
In the question, we have to find out the absolute pressure at the evacuated region of the tank if the temperature is a constant.
Provided, the tank is partially filled with water at 80℃.
The saturation pressure of water at 80℃ is, Psat = 47.34 kPa
