  • T(oC) = 5/9[T(oF) - 32]

Heating Energy

The energy required to heat a product can be calculated as

q = cp m dt   (1)

where

q = heat required (kJ)

cp = specific heat (kJ/kg K, kJ/kg oC)

dt = temperature difference (K, oC)

Example - Required Heat to increase Temperature i Water

10 kg of water is heated from 20 oC to 100 oC - a temperature difference 80 oC (K). The heat required can be calculated as 

q = (4.19 kJ/kg K) (10 kg) (80 oC)

  = 3352 kJ
