Consider a thin‐walled, metallic tube of length l = 1 m and inside diameter di = 3 mm. water enters the tube at ˙ m = 0.015 kg / s m˙=0.015 kg/s and tm, i = 97°c. a. 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 layer of insulation of k = 0.05 w/m-k is applied to the tube and its outer surface is maintained at 27°c, what is the outlet temperature of the water? c. if the outer surface of the insulation is no longer maintained at 27°c but is allowed to exchange heat by free convection with ambient air at 27°c, what is the outlet temperature of the water? the free convection heat transfer coefficient is 5 w/m2 -k.
