Atank initially contains 12.5 kg water at 2 bar and the quality is 65%. the tank is connected to a steam pipe with a valve and initially the valve is closed. the pipe is carrying steam at 15 bar and 240°c. the valve is then opened until the until the tank pressure reaches 7 bar, at which time the valve was closed, and the tank temperature has reached 200°c.
(a) determine the volume of the tank in cubic meters.
(b) determine the final mass in kg.
(c) determine the heat transfer between the water in the tank and its surroundings (in kj) that occurred while the valve was open. tea m 15bar 2400 va\ve ,q=? tank
