A stainless steel (AISI 304) tube used to transport a chilled pharmaceutical has an inner diameter of 36 mm and a wall thickness of 2 mm. The pharmaceutical and ambient air are at temperatures of 6°C and 23°C, respectively, while the corresponding inner and outer convection coefficients are 400 W/m^2·K and 10 W/m^2·K, respectively. Required:a. Evaluate the properties of the stainless steel at T = 280 K. b. What is the heat gain per unit tube length? c. What is the heat gain per unit length if a 10-mm-thick layer of calcium silicate insulation (k_ins = 0.050 W/mK) is applied to the tube?
