Question

Steam at atmospheric pressure (Tsat = 100oC, hfg = 2.257×106 J/kg) is in contact with a horizontal tube through which a cooling fluid is circulated. The tube has 0.0334 m outside diameter, 1 m length, and an outside-surface temperature that is maintained at 60oC. Determine the rate of heat that the cooling fluid must remove and the condensation rate. For water at average temperature, ρ L = 974 kg/m3, k = 0.668 W/m·K, ρ v = 0.516 kg/m3, ν L = 0.364×10-6m2/s. g =9.81 m/s2.

An aluminum saucepan has a handle that is fixed to its wall. The handle itself is made of low carbon steel, and will have a plastic grip attached to it that is comfortable to grasp. Before selecting a plastic, it is necessary to have information on the temperature of the carbon steel handle. The carbon steel handle can be considered as a rod 11 mm in diameter and 45 mm long. When being used over a stove burner, the ambient temperature T∞ is 30 oC, and the temperature at the base of the handle reaches T0 = 100 oC. The convective heat transfer coefficient h is 8 W/m2·K and k = 43 W/m·K for low carbon steel. Can you derive the differential equation for the temperature of handle with x as a spatial variable and determine the temperature of handle at the position of 40 mm from the base.
