A steam-powered lift system (figure) leverages steam flowing through a pipeline at 1 MPa and 400C to lift objects using a simple piston-cylinder configuration. To lift an object, it is placed on the piston and then the throttling valve is opened. Steam slowly flows into the well-insulated cylinder from the pipeline and lifts the object to the desired height, after which the valve is shut. The massless piston has a cross-section of 100 cm2 and the atmospheric pressure is 100 kPa. A. If the cylinder is initially evacuated, what is the final temperature of the water in the cylinder after lifting a 2 kN object? B. How much water, in kg, is needed to lift the 2 kN object 10 m
