Energy Requirement for a Heating Up Application

Energy required heating up a substance

The energy required heating up a substance like a tank, swimming pool or similar within a certain time can be calculated as

q = m c_p dt / t  (1)

where

q = mean heat transfer rate (kW)

m = mass of substance (kg)

c_p = specific heat capacity of the substance (kJ/kg ^oC)

t = heat up time (s)

Note that heat loss to the surroundings will extend the heating up time.
