A75-kW, 3-phase, 440-V (line to line), 4-pole, 60 Hz Y-connectedinduction motor. When the motor runs at 1710 rpm, the line currentdrawn from the supply is 78 A at 0.85 PF lagging. Given that,stator iron loss is 2kW, windage and friction losses are 1.2kW andresistance between two stator terminals = 0.4W, Calculate:a. Synchronousspeed b. Slip c. Electrical input power tothemotor d. Stator copperlosses e. Power supplied to therotor f. Rotor copperlosses g. Mechanical power supplied totheload h. Efficiency of themotor i. Torque developedat rotor speed 1710rpm j. Draw the power flow diagram
a closed conical tank with diameter of 1.50 and height of 3.00 m, sitting on its circular base has 1.00m depth of water. Suppose the tank is upside down and is made to stand vertically that way using some device.
Construct a ladder schematic with a holding circuit to energize a relay. The relay when enerigized will turn one of and turn a different lamp on.
