Q1. A factory has a 240V supply from which the following loads are taken: Lighting: Three hundred 150 w/each, four hundred 100 w/each and five hundred 60w/each lamps. Heating: 100 kw. Motors: A total of 44.76kw (60HP) with an average efficiency of 75%. Others: various loads taking a current of 40A. Assuming that The lighting load is on for a period of 4hours /day. > The heating for 10 hours / day and the remainder for 2 hours / day. Calculate 1. The weekly consumption of the factory in kWh when working on a 5 day/week. 2. What current is taken when the lighting load only is switched on?

13). A motor with power factor of 0.85 is served by a single- phase 120 V source; the motor requires 3000 W of input power to deliver 2500 W output power. a) What is the efficiency of the motor? b) What is the line current drawn by the motor? p. 1
An electric motor with a maximum output of 75 hp (horse power, English: hp, horse power) on the axle has an efficiency of 91%. It will be replaced with a new motor, which has the same maximum shaft power, but an efficiency of 95.4%. The old engine has been in operation for 5000 hoursper year with at 80% of its maximum effect (ie '80% load' or '80% load factor'). The new engine must run with the same load and the same number of hours.a) How much electrical energy is saved per year by replacing the old one with the new motor?b) How much expenditure on electricity is saved by replacing the old with the new motor whenelectricity price is $0.14/kWh?
