A cylindrical vessel with a diameter of 8 inches and 5 feet long contained acetylene at 300 psi gauge and 82°F. After some amount of acetylene was used, the pressure was reduced to 190 psi gauge and the temperature was 74°F. The gas constant of acetylene is 59.35 ft-lbf/lbm-°R. Determine the following: What is the initial mass in lbm of the acetylene inside the vessel What proportion in percentage of acetylene was used? What volume in ft3 would the used acetylene occupy at 30 psig and 80°F?

Answer the following questions with solution/ detailed explanation: 1. The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25°C, the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tire rises to 50°C. Also, determine the amount of air that must be bled off to restore pressure to its original value at this temperature. Assume the atmospheric pressure to be 100 kPa.
