An hydrogen vapour container is mounted with a pressure gauge which shows 86 bar. Then its absolute pressure is bar Pressure in bar

H.W.1/: The air in an automobile tire with a volume of 2.60 ft3 is at 90°F and 20 Pisa. Determine the amount of air that must be added to raise the pressure to the recommended value of 30 Pisa. Assume the atmospheric pressure to be 14.6 Pisa and the temperature and the volume to remain constant?

4. In a condenser containing air and water, the air pressure is 22 kpa absolute. What is the gage pressure in kpa at a point 1.5 m below the water surface

5. A gas is initially at a gauge pressure of 400 kPa. What is its final gauge pressure if its volume is reduced by half? Presume that the atmospheric pressure is 101.3 kPa. 800 kPa a. b. 698.7 kPa C. 901.3 kPa None of the above
