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

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
