An Indoor Experimental Determination of Thermal Efficiency of a Cooking Stove

Nathaniel Muwa Shawhatsu

Abstract: Certain mil of water were heated to complete evaporationindoor inside an opening 4 liters cooking pot using a three (3) liters kerosene stove whose wicks were adjusted to a fixed level. On complete evaporation of 50 mL, 75 mL and 100 mL, the internal and external temperature of the pot and time taken were recorded and the measured parameter were used to calculate the quantity and the rate of heat energy supplied by the stove. The quantities of heat calculated for each mil of water evaporated are: 177394 J, 237300 J and 296596 J respectively, while the thermal power supplied by the stove is 664 J/s.
