As shown in the figure below, air is contained in a vertical piston-cylinder assembly such that the piston is in static equilibrium. The atmosphere exerts a pressure of 14.7 lbf/in.2 on top of the 4-in.-diameter piston. The absolute pressure of the air inside the cylinder is 20 lbf/in.2. The local acceleration of gravity is g = 32.2 ft/s². P= 14.7 lbf/in.²
