It is given that an insulation (kI = 0.232 W/m K) is put on a steel pipe (1.6 cm ID and 2 cm OD). Hot water at 90°C flows through the pipe and the heat transfer coefficient on hot water side (hi) is 580.55 W/m2 K. Heat is lost from the outer surface by natural convection to surrounding air at 30 °C and ho = 11.61 W/m2 K. Calculate the heat loss rate per meter length of the pipe for insulation thickness values of 0, 0.5, 1, 2, 3, 4, 5 and 6 cm. Plot the results and discuss the variation obtained.
