One kg bone-dry cotton fabric is padded with water to obtain 80% wet pick up. The temperature of the wet fabric after padding is 30oC. Assume the specific heat of water to be 1 cal/(gβ
oC); the latent heat of evaporation of water to be 540 cal/g and the specific heat of cotton to be 0.3 cal/(gβ
oC). The energy (kcal) required to dry the fabric completely (in integer) is _______.
Correct : 462
