10-40 In a gas-fired boiler, water is boiled at 150°C by
hot gases flowing through 25-m-long, 5-cm-outer-diameter
mechanically polished stainless steel pipes submerged in
water. If the outer surface temperature of the pipes is 160°C.
determine (a) the rate of heat transfer from the hot gases to
water, (b) the rate of evaporation, (c) the ratio of the critical
heat flux to the present heat flux, and (d) the surface tempera-
ture of the pipe at which critical heat flux occurs.
