1. A 3-phase, 16 hp, 460V, 4-pole, Lottz, Full output power to a load connected to friction loss of the motor is 758 w. power developed (b) Air cap power (c) rotor copper loss. 1788 rpm induction motor delivers it's shapt. The windage and Determine the (a) mechanical 2. Plastic kayaks are manufactured using process called rotomolding. Molten plastic is injected into a mol, which is then spun on the long axis of the Kayak until the plastic cools, resulting in a hollow one-piece craft. Suppore that the induction motors used to spin the molds consume a PF OF 0.88 lagging from a JkW at 220LO Vrms, 60Hz line. Determine the (a) capacitor bank to be placed in parallel with the load to increase the pF to 0.98 lagging. What is the new reactive power ?
