Page 29 Exercise Sheet 12. olve the following problems. Provide correct units with answers. 1. If atmospheric pressure is 14.7 psi and the gauge pressure is 64 psi, what is the total or absolute pressure? 2. If atmospheric pressure is 14.7 psi and the absolute pressure inside a container is 69 psia, what would a gauge read? 3. 24 cubic feet of a gas at a gauge pressure of 246 psig is compressed to 6 cubic feet. After the temperature has cooled to the original value, what will be the new gauge pressure? The atmospheric pressure is 14.7 psi. 4. 34 cubic feet of a gas at a gauge pressure of 146 psig is compressed to 6 cubic feet. After the temperature has cooled to the original value, what will be the new gauge pressure? The atmospheric pressure is 14.7 psi. 24 cubic feet of a gas at a gauge pressure of 460 psig is allowed to expand to 36 cubic feet. After the temperature has warmed to the original value, what will be the new gauge pressure? The atmospheric pressure is 14.7 psi. 6. 14 cubic feet of a gas at a gauge pressure of 600 psig is allowed to expand to 56 cubic feet. After the temperature has warmed to the original value, what will be the new gauge pressure? The atmospheric pressure is 14.7 psi. 7. A 10 cubic foot container of gas at 70 degrees F is heated to 140 degrees F. The pressure will held constant by allowing the volume to expand. To what new volume will the gas expand? 8. A 10 cubic foot container of gas at 80 degrees F is heated to 160 degrees F. The pressure will held constant by allowing the volume to expand. To what new volume will the gas expand? A 20 cubic foot container of gas at 80 degrees F is heated to 120 degrees F. The pressure will held constant by allowing the volume to expand. To what new volume will the gas expand?
