Concept explainers

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.

Question

A 57.87-hp motor that has an efficiency of 92.84% is soon to be obsolete. It will be replaced by a high efficiency motor which is 96.7% efficient. The motor operates 4,430 hours a year. Taking the cost of electricity to be Php 9.18 per kWh, compute the annual savings due to the installation of the high efficiency motor instead of the standard motor. Round your answer in 2 decimal places only.
