1. A closed rigid tank has a capacity of 2.5 m3. It holds air at 400 kPa and 18 deg C. Heat is added until the temperature is 350 degC. Determine the heat added in kJ.


2. Given a vacuum pressure of 165 mmHg. The barometric pressure is 745 mmHg. Find the absolute pressure in kPa.


3. What is the amount of dry steam flow to an engine, which is supplied with 4500 kg per hour wet steam with a quality of 80%?
