2 Boilpipe Water flows through a circular pipe of length 10 m and diameter 6 cm. The volume flow rate of water is 2.5 Ls-1: The water enters the pipe at 10°c. Outside the pipe, R-134a refrigerant condenses with a saturation temperature of 52°C. Neglect conduction through the pipe wall - that is, the interior of the pipe is at that same temperature. Assume the viscosity of water is vw = 0.000001 m’s-1, the thermal conductivity of water is kw = 0.6 W m-4K-1, and the Prandtl number of water is Prw = 6.9, the density of water is pw = 1000 kg m-3, and the specific heat of water is cw = 4200 J kg-?K-1 The Dittus-Boelter equation should be used to determine any Nusselt number: Nud = 0.023Red // Pr” where n = 0.3 for a fluid cooling off and n = 0.4 for a fluid that is heating up. Determine the outlet temperature of the water and the rate of heat transfer. For a point of extra credit, if the latent heat of evaporation of the R-134a is hfg = 148.66 kJ kg", determine the rate of condensation of R-134a, in kg s-1, = a mis Inom kam?
