9) Electrical power is to be generated by installing a hydraulic turbine-generator at a site 70 m below the free surface of a large water reservoir that can supply water at a rate of 1500 kg/s steadily. If the mechanical power output of the turbine is 800 kW and the electric power generation is 350 kW, determine the turbine efficiency and the combined turbine-generator efficiency of this plant. Neglect losses in the pipes. (10pts).

The battery voltage in the following figure is E-24V and its capacity is 300Wh. The average charging current should be Idc-25A. The primary input single-phase voltage is Vp-120V, 60Hz, and the transformer has a turns ratio of h-3:1. Determine: (1 ) the conduction angle of the diode; (2) the current-limiting resistance R (to limit charging current under 25A); (3) the power rating PR of R (4) the charging time tc in hours; (5) the rectifier efficiency η; (6) the peak inverse voltage (PIV) of the diode...
