QUIZ 1 Insulation (k= 0.20 k/w-m is put on a steel pipe (d; = 1.6 cm, do = 2 cm). Hot water at 90°C flows through the pipe with a heat transfer coefficient h₁ = 500 w/m²-K. Heat is lost by convection from the outer surface to air at 30°C with a heat transfer coefficient ho = 10 w/m²-K. Calculate the rate of heat loss per meter length of the pipe for no insulation, for 1 cm and 2 cm thick insulation and explain the results. 1001
