Question: Please show all steps on how answers were found. will also rate the question, thank you! class is Heat Transfer a 2. Water at a
a 2. Water at a temperature of 100 C having a thermal conductivity of 0.630 W/m C flows inside a 10 meter long 1" schedule 80 stainless (1%C) pipe at a rate of 30 kg/min. Air at 25 C flows across the outside surface of the pipe at a velocity of 10 m/s. If the thermal conductivity of the steel is 43 W/mC and the convection heat transfer coefficients between (water and pipe) and (air and pipe) are 3,500 W/m2C and 100 W/mC, respectively. (a) Draw the electric circuit of the heat transfer. (10 points) (b) Calculate the thermal resistances in the circuit and the heat loss rate from water to air per meter of the pipe. (20 points) (c) Find out the temperatures T, and TM on the inside and outside walls. (10 points) (d) What are the overall heat transfer coefficients U.?
