Waler at a mass flow rate of m = 0.3 kg/s to be heated from 20°C to 60°C by
passing it through a thin-walled tube of diameter D = 20 mm. Steam is used
for heating by condensing outside the thin walled tube at a temperature
130°C. For an overall heat transfer coefficient of 650 W/m?.K. Determine the
length of the tube required to achieve it.
