A rigid container equipped with a stirring device contains 2.7 kg of motor oil. Determine the rate of specific energy increase when heat is transferred to the oil 3t a rate of 3W, and 4.5W of power is applied to the stirring device.

Solution

ENERGY INCREASE=POWER-HEAT =4.5-3=1.5W

SPECIFIC ENERGY INCREASED=1.5/2.7=0.5556W/KG
