inlet temperature of 97°C. ) What is the outlet temperature of the water if the tube surface temperature is maintained at 27°C? (b) If a 0.5 mm thick insulation layer (k=0.05 W/m-K) is applied to the tube and the outer surface of the insulation is maintained at 27°C, what is the outlet temperature of the water? (Hint: review the last part of Ch. 8.3.3). Ans: 95.8°C Ans:(c) If air blows perpendicular to the insulated pipe axis with a velocity of 10 m/s and a free stream temperature of 27°C, what is the outlet temperature of the water?
