Referring to the figure below, the tank is being filled with water by two one- dimensional inlets. Air is trapped at the top of the tank. The water height is h. Compute for dh/dt if D₁ 1 in, D₂ = 3 in, V₁ = 3 ft/s, V₂ = 2 ft/s, and At = 2 ft² (tank surface area). The change in water height is obtained from the relation;

The pump-turbine system in the figure draws water from the upper reservoir in the daytime to produce power for a city. At night, it pumps water from lower to upper reservoirs to restore the situation. For a design flow rate of 33.4 cfs (ft³/s), the friction head loss is 17 ft. Estimate the power in horsepower delivered by the pump (W yQhp). Use y = 62.4 lbf/ft³; 1 hp A. 409.3 B. 538.1 OA B U OD 7 550 ft·lbf/s) C. 473.7 O Water at 20°C D. None of the above Z, 150 ft Pump- turbine 1 2₂-25 ft
