Modelling a Process - A Tank Heating System

Modelling a Process - A Tank Heating System

Hot water is used to heat the contents of a reactor. It is supplied to the jacket at a temperature of Ts. Heat is transferred at a rate of Qin (J/sec = Watts) from the jacket to the reactor contents. This input causes a change in the reactor temperature, T. The liquid in the reactor has a mass, m (kg), and a specific heat capacity of Cp (kJ/kgK).
