A single-cylinder vertical atmospheric engine with a 1.2m bore and a piston of 2700 kgmass is used to lift a weight. Pressure in the cylinder after combustion and cooling is 22kPa, 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 andthe piston moves up. [kg](b) Mass which can be lifted if the vacuum is at the bottom of the cylinderand the piston moves down. [kg]
