Steam flows at a temperature of 550C through a pipe (k-80w / mK) with inner and outer diameters of 5 cm and 5.5 cm. The pipe is covered with 3 cm thick glass wool with a heat transfer coefficient of 0.05 W / mK. Since the heat transfer coefficient on the inner surface of the pipe is 600 W / m'K, the external ambient heat transfer coefficient is 35 W / m'K and the ambient temperature is 15C; a) It does not calculate the amount of soot that passes through a unit length of pipe. b) Examine the insulation made by calculating the critical insulation radius
