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 24 lbf/in.². The local acceleration of gravity is g = 32.2 ft/s². Determine the mass of the piston, in lb. Mpiston Determine (a) the mass of the piston, in lb, and (b) the gage pressure of the air in the cylinder, in psig p(gage) = lb Determine the gage pressure of the air in the cylinder, in psig. 1 P14.7² g=322 06² psig D Air P
