Hot water at T; = 120° C flows in a stainless steel pipe (k = 15 W/m. °C) whose inner diameter is 1.6 cm and thickness is 0.2 cm. The pipe is to be covered with adequate insulation so that the temperature of the outer surface of the insulation does not exceed 40° C when the ambient temperature is T, = 25° C. Taking the heat transfer coefficients inside and outside the pipe to be h; = 70 W /m2 . °C and h, = 20 W /m2. °C, respectively, determine the thickness of fiberglass insulation (k = 0.038 W/m. °C) that needs to be installed on the pipe. 40°C Steam Insulation R, R, R.
