In a system, process stream is heated to a specific temperature and after heating, it is sent to another process. Process stream is fed to the system at 25oC and with 15 m3 /h flow rate. Volume of the tank is 120 m3 . Density of the fluid is 1 g/cm3 , heat capacity is 0.8 kcal/kg, flow rate of saturated steam is 800 kg/h and saturated steam enthalpy is 960 kcal/kg. It is known that the heat capacity and
