A 50V DC source is connected in series with a switch, an 8.2k ohm resistor, and a 0.01 microfarad capacitor. There is no initial charge on the capacitor and the switch is open. Determine both A & B The time at which the capacitor is fully charged
Steam at 160 bar and 480oC enters a turbine operating at steady state with a volumetric flow rate of 800 m3/min. Eighteen percent of the entering mass flow exits at 5 bar, 240oC, with a velocity of 25 m/s.
A 220V , 13.47KVA, 0.707 lagging power factor load is in parallel with a three phase wye- connected round rotor synchronous motor having a synchronous reactance of 1.27W. The motor draws 33KW at apower angle of 30 degree.
