Question 1: Air is contained in a vertical piston-cylinder assembly such that the piston is in static Pam =101 kPa equilibrium. The atmosphere exerts a pressure of 101 kPa on top of the 15-cm-diameter piston. = 9.81 m/s Driston = 15 cm. The absolute pressure of the air inside the cylinder is 110 kPa. The local acceleration of gravity is g = 9.81 m/s². Determine (a) the mass of the piston, in kg, and (b) the gage pressure of the air in the cylinder, in kPa. Air P= 110 kPa
