Please show detailed work and write clearly. Thank you.
6. A four-pole squirrel-cage motor has the following characteristics: Power input at a rated load is 5200 W with a power factor of 0.70. Rated speed is 1150 rpm. Resistance of each stator windings (there are three) is Rs-: 0.195 Ω. . The motor is supplied by a three-phase source with a line-to-line voltage of 460 V and a frequency of 50 Hz. The windings of the motor have a Y-connection....

homework for me! I will like you answer if correct!
For the questions on this page, assume that that an induction motor is rated to deliver 10kW (approximately 13.3HP} when operated at 240VRMS 60Hz. The motor has a lagging power factor of 0.8. The building electrical service only supplies 208VRMs, so the motor can not be connected directly to the electric service. An ideal transformer is used to create...

Two 180-horsepower (HP) motors are being considered for installation at a municipal sewage-treatment plant. The first costs $6,300 and has an operating efficiency of 77%. The second costs $3,600 and has an efficiency of 70%. Both motors are projected to have zero salvage value after a life of 10 years. If all the annual charges. such as insurance maintenance, etc., amount to a total of 13% of the original cost of each motor, and if...

2. At the power plant, the water for cooling must be removed at a minimum rate of 65 gal/min. A pump is found in storage that has a displacement of 4.8 ins/rev. A motor is also found; it operates at 960 rpm, 230 VAC, and 22.5 A. The power factor on the motor has an overall n=89%. If a 4" pulley is attached to the motor, what size pulley should be attached...
