Question
Problem Solving. Solve the following problems completely.
5. Motors from two different manufacturers are being considered for application.
Both motors are 50Hp, 460 volts, 3 phase, 60 cycles. Motor A operates at 80%
efficiency and motor B operates at 89% efficiency. The expected need for the
motor is 15 years. Motor A cost P120, 000.00 and motor B P150, 000.00.
Electrical energy cost P8.00 per Kw-Hr and the motors will be operating 8 hours
per day, 250 days a year. Assume taxes and insurance are 3% of first cost. Which
motor should be purchased?
