The surface temperature of a 10 m long and a 6-cm-diameter horizontal hot water pipe is 73 ℃. Assume the air temperature to be 27 ℃. Determine the rate of heat loss from the pipe by free convection. Properties of Air are: k = 0.02735 W/m.℃, ν = 1.798*10^-5 m2/s, Pr = 0.7228, β= 1/Tf = 0.003096 K^-1.
