6. A vessel with a paddle agitator and no baffles is used to heat a liquid at 37.8C in this vessel. A steam heated jacket furnishes the heat. The vessel inside diameter is 1.22 m and the agitator diameter is 0.406 m and is rotating at 150 rpm. The wall surface temperature is 93.3C. The physical properties of the liquid are p = 977 kg/m', cp = 2.72 kJ/kg-K, k = 0.346 W/m-K, and u = 0.100 kg/m-s at 37.8C and 7.5 10 at 93.3 C. Calculate the heat transfer coefficient to the wall of the jacket. X
