A single-cylinder vertical atmospheric engine with a 1.2 m bore and a piston of 2700 kg mass is used to lift a weight. Pressure in the cylinder after combustion and cooling is 22 kPa, while ambient pressure is 98 kPa. Assume piston motion is frictionless. Calculate:
(a) Mass which can be lifted if the vacuum is at the top of the cylinder and the piston moves up. [kg]
(b) Mass which can be lifted if the vacuum is at the bottom of the cylinder and the piston moves down. [kg]
