The figure below shows a turbine-driven pump that provides water to a mixing chamber located dz = 25 m higher than the pump,
where in = 20 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.

- 3. A hydraulic lift is shown below. The combined mass of the piston, rack, and car is 4000 lbm. The working fluid is water. There is no heat transfer to or from the water, and the internal energy of the water per unit mass is constant. The water may be considered incompressible. (a) Taking all the water in the reservoir, line, and hydraulic cylinder as the system (i.e., taking the closed-system approach), calculate the work necessary to raise the rack and car 1 ft (neglect the change in potential energy of the water in the system). (b) Repeat part (a), taking all the water plus the car and the rack as the system. (c) Repeat part (a), taking an open-system approach; choose as your system the volume of the hydraulic cylinder, excluding the piston, rack, and car. If the absolute pressure in the system is 1000 lbf/in², calculate the volume that must flow in to raise the car 1 ft.
