4. A company currently uses a 75 hp motor with an efficiency of 92.25% running continuously at full load. They plan to purchase a new 100 hp motor with an efficiency of 94%. The new motor will run continuously at 80% of the full load. The electricity consumption rate is $0.0875/kWh and an annual demand rate is $4.55/kW. a. Calculated the annual savings. b. The purchaser is presented with the following option, compute the SPP of each and indicate which one should be selected. • Purchase price of $24,500 • Purchase price of $28,000 and an $8/hp rebate

A 54.52-hp motor that has an efficiency of 90.72% is soon to be obsolete. It will be replaced by a high efficiency motor which is 96.08% efficient. The motor operates 4,378 hours a year. Taking the cost of electricity to be P8.92 per kWh, compute for the annual savings due to the installation of the high-efficiency motor instead of the standard motor. Round your answer into two decimal places only.
