Two tanks contain steam, and they are both connected to a piston/cylinder. Initially the piston is at the bottom and the mass of the piston is such that a pressure of 1.4 MPa below it will be able to lift it. Steam in A is 4 kg at 7 MPa, 700?C and B has 2 kg at 3 MPa, 350?C. The two valves are opened, and the water comes to a uniform state. Find the final temperature and the total entropy generation, assuming no heat transfer.
the open water tank is resting on a frictionless plane. the capped orifice on the side has a 4-cm diameter exit pipe
an engineer has proposed that a simple ideal rankine cycle that uses refrigerant 134a be used to produce work with heat
Consider this multi-fluid container that contains fluids of different SGs as shown except for one fluid. Given that the pressure measured by the gage is 15.5 psia and the pressure in the container is 108.55 kPa, calculate the specific gravity of the ..
A piston cylinder device initially contains 0.071m^3 of nitrogen gas at 140kPa and 135 degrees C. The nitrogen is now expanded to a pressure of 80kPa polytropically with a polytropic exponent whose value is equal to the specific heat ratio. Determine..
