Steam at a temperature of 250°c flows through a steel pipe (aisi 1010) of 60 mm inside diameter and 75 mnm outside diameter. the inside heat transfer coefficient is 500 w/m2.k. the steel pipe is insulated from outside with 3.75 cm 85% magnesia insulation. the outside heat transfer coefficient is 25 w/m2.k and the insulation emissivity is 0.8. the temperature of the outside air and the surrounding is 20°c (a) draw a clear schematic with all its details. (b) draw a clear thermal circuit network with all its details. (c) obtain the temperature expression with which one can calculate the outside temperature ts o. but do not calculate t. s, o
