Question

A steel pipe (k= 35 W/m K) with inner diameter 50 mm and outer diameter 60 mm is insulated using insulation material having (K=0.055 W/m.K). The temperature interface between pipe and insulation is 573 K, while the temperature on outside of insulation must not exceed 343 K, with permissible heat loss of 700 W/m. calculate (1) the minimum thickness of insulation and (2) the temperature of inside surface of pipe
