A-95°C hot water is flowing inside a stainless-steel pipe exposed to an opened space. The thickness of the pipe is 2.5 cm and the convection heat transfer coefficient for hot water and air are 88 W/m2 ·°C and 19 W/m2 ·°C, respectively. Propose how would you reduce the heat loss of the pipe by 85%. Indicate all the assumptions used in your proposal with detailed calculation steps.
