To compute the energy used by a motor, multiply the power that it draws by the time of operation. con- sider a motor that draws 12.5 hp for 16 h/day, five days per week. compute the energy used by the mo- tor for one year. express the result in ft. lb and w. h

E=52000Hp.h

E=38724920Wh

E=1.028x10^11 ftlb

Explanation:

To solve this problem you must multiply the engine power by the time factor expressed in h / year, to find this value you must perform the conventional unit conversion procedure.

Finally, when you have the result Hp h / year you convert it to Ftlb and Wh

E=52000Hp.h

E=38724920Wh

E=1.028x10^11 ftlb
