An organic liquid is boiling at 340 K on the inside of a 3-mm thick metal surface (thermal conductivity 42 W/m.K). The outside of the surface is heated by condensing steam. The coefficients of heat transfer from the inner metal surface to the boiling liquid depends upon the temperature differences as listed in the table below: Temperature Difference Between Metal Surface and Boiling Liquid (in K) Heat Transfer Coefficient for Metal Surface to Boiling Liquid (in kW/mK) 22.2 27.8 33.3 36.1 38.9 41.7 44.4 50.0 4.43 5.91 7.38 7.30 6.81 6.36 5.73 4.54 Assuming the heat transfer coefficient from the condensing steam to outside metal surface is constant at 11 kW/m.K, find the value of steam temperature would give a maximum rate of evaporation.
