A pumped storage facility uses a 6.6 kV, 60 Hz, 4200 kVA, 3360 kW, 10 pole, three-phase synchronous machine, with a synchronous reactance of 1.13 pu. Assume a cylindrical rotor. The hydro turbine is rated 3500 kW. All losses are neglected. 1. Hydro generator capabilities (a) Compute the hydro turbine speed to obtain a 60 Hz output; the range of the power factor of the generator; the rated line current. Compute the value of synchronous reactance in ohm. (b) Draw the per-phase equivalent circuit. Assume Y-connected generator windings. Present and explain the functions of the hydro turbine and generator controls.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
