Water flows through a 10cm steel pipe (k-16 W/m-K) wrapped with a layer of 5- cmthick insulation (k=0.1W/m- K). The heat transfer coefficient inside and outside the pipe is 2000W/m²K and 200W/m²-K, respectively. Determine the heat flow through the pipe if the water is at 80°C and the air outside is at 20°C.
