Superheated steam at an average temperature of 110°c is transported through a steel pipe (k = 50 w/m·k, do = 8.0 cm, di = 6.0 cm, and l = 20.0 m). the pipe is insulated with a 4-cm-thick layer of gypsum plaster (k = 0.5 w/m·k). the insulated pipe is placed horizontally inside a warehouse where the average air temperature is 10°c. the steam and the air heat transfer coefficients are estimated to be 800 and 200 w/m2·k, respectively. calculate the daily rate heat transfer of the steam.
