A steady-state flow process is used to heat methanol in a tank. The incoming stream is at 2 bar and 25 oC and has a flow rate of 5 kg/s. The outgoing stream is at 1 bar, 100 oC. Heating is provided by a heating coil immersed in a tank. Given the following data, calculate the amount of heat required for this process.
Methanol at 2 bar:
Boiling point is 83 oC
Heat capacity, vapor, is 60 J/mol/K
Heat capacity, liquid, is 80 J/mol/K
Heat of vaporization is 36740 J/mol
