A gas cylinder with interior volume 11.6 L holds compressed air at 17.4 MPa. The cylinder is joined by a hose of negligible volume to a second cylinder that’s been pumped down to vacuum. When the valve on the full cylinder is opened, the air expands to fill the entire system, all the while maintaining a constant temperature. If the energy that becomes unavailable to do work is 171.8 kJ, what’s the volume of the second cylinder (L)?

Between 1-2: Isothermal compression (1st process)Between 2-3: Isometric compression (2nd process)Between 3-1: Adiabatic expansion (3rd process) A cyclic process through which N2 gas, which is considered to be the ideal behaving, is treated, has been described above. In case 1, the volume of gas is 9.6 m3, pressure 200 kPa. Since the pressure in state 3 is 750 kPa, find the work done in the whole process in kJ. Draw the P-V diagram for the cycle.

The figure below shows a turbine-driven pump that provides water to a mixing chamber located dz⁢= 5 m higher than the pump, where m˙=50 kg/s. Steady-state operating data for the turbine and pump are labeled on the figure. Heat transfer from the water to its surroundings occurs at a rate of 2 kW. For the turbine, heat transfer with the surroundings and potential energy effects are negligible. Kinetic energy effects at all numbered states can be ignored. Determine:(a) the magnitude of the pump power, in kW.(b) the mass flow rate of steam, in kg/s, that flows through the turbine.
