A50-mm-diameter, thin-walled metal pipe covered with a 25-mm-thick layer of insulation (0.085 w/m k) and carrying superheated steam at atmospheric pressure is suspended from the ceiling of a large room. the steam temperature entering the pipe is 120°c, and the air temperature in the room is 20°c. the convection heat transfer coefficient on the outer surface of the covered pipe is 10 w/m2 k. the velocity of the steam in the pipe is 10 m/s. the steam temperature at the outlet of the pipe is at tmo =106°c 1. calculate the mass flow rate of steam in the pipe. 2 calculate the total ua for the entire pipe 3 calculate the internal heat transfer coefficient hi 4 construct a resistance model and calculate the resistances “r” that affect the heat transfer from the steam to the outside air. 5 calculate the length of the pipe. 6 calculate the temperature of the pipe's surface at the exit of the pipe (tso) using the resistance model at the outlet of the pipe. 7 what would happen if tmo was cooler than 106°c?
