Steam at 1 bar enters an adiabatic heat exchanger with a quality of 0.896 and exits as a saturated liquid. The steam is being cooled by a 861 kg/s stream of water which enters the heat exchanger at 20oC and exits at 40oC. The two flows do not mix. Determine the volumetric flow rate (m3/s) of the steam entering the heat exchanger.
(1) I shte cooling process polytropic? If so, what is the value of n? (2) Find the final state pressure. (3) Compute the work done for this process considering the water as a closed system.
Determine the minimum distance from a 50 ft height building from which the ball can be thrown and not hit the side of the building , but it may land on the roof depending upon how long the building is.
