A jacketed-agitated vessel, fitted with a turbine agitator, is used for heating a water stream from 10C to 54C. The tank diameter D= 0.6 m, height H= 0.6 m, and agitator diameter D = 0.2 m. Saturated steam at 100C condenses in the jacket. (The specific heat of water at the average temperature of 32C is 4178 J/kg-C.) The properties of water at 54C are k=0.648 W/m C p = 985.8 kg/m u = 0.513 10-3 kg/m-s Pr = 3.31 If the agitator speed is 70 rpm, determine the heat transfer coefficient on the inner wall of the vessel. (Round the answer to the nearest whole number.) (You must provide an answer before moving to the next part) The formula Nu = 0.76Re 2/3p+1/3 can be used in calculations. Evaluate the Reynolds number based on the tank diameter. The heat transfer coefficient on the inner wall of the vessel is W/m.C. The overall heat transfer coefficient, neglecting the wall resistance and the thickness of the wall, is 3692.8775 W/m.C. Calculate the mass flow rate of water that can be heated in this agitated vessel steadily. (Round the final answer to the nearest whole number) (You must provide an answer before moving to the next part) The mass flow rate of water that can be heated in this agitated vessel is kg/h.
