1. A flat base agitated jacketed vessel with an 8 ft diameter (dr) contains 3,000 US Gal of process fluid having the properties listed below. The agitator is a retreat blade turbine, 3 ft in diameter turning at a speed of 50 rpm. Neither the vessel or the jacket contain baffles. The inside (d) and outside (do) diameters of the jacket are 8 ft and 8.5 ft respectively. The process fluid is being heated by a mixture of ethylene glycol and water, having the properties shown below. Given that the jacket completely engulfs the vessel and there is no viscosity correction for either the vessel content or jacket fluid (i.e. lxw = 1) calculate the following: (a) The overall heat transfer coefficient, given the Nusselt correlations below. (10 marks) Fluid properties of the vessel contents: Density, p=45 lb/ft Viscosity, y = 10 lb/ft.h Specific heat, C=0.7 Btu/lb. "F Thermal conductivity, k = 0.42 Btu/h.ft. "F Fluid properties of the jacket contents: Density, p=62.427 lb/ft! Viscosity, y = 0.03 lb/ft.h Specific heat, C = 0.905 Btu/lb." Thermal conductivity, k = 0.13 Btu/h.ft. "F The Nusselt expression relevant for the inside vessel geometry is: Nu = - na
