Pressure inside?

Problem 01.064 - Pressure inside a piston-cylinder device The piston of a vertical piston-cylinder device containing a gas has a mass of 150 kg and a cross-sectional area of 0.04 m , as shown in the figure. The local atmospheric pressure is 0.97 bar, and the gravitational acceleration is 9.81 m/s2 Patm = 0.97 bar m A =0.04 m2 P = ? Problem 01.064.a - Pressure inside a piston-cylinder device Determine the pressure inside the cylinder. (Round the final answer to three decimal places.) The pressure inside the cylinder is 36.788 * bar
