A vessel with a paddle agitator and no baffles is used to heat a liquid at 37.8degC in this vessel. A steam-heated jacket furnishes the heat. The vessel inside diameter is 1.22 m and the agitator diameter is 0.406m and is rotating at 150 rpm. The wall surface temperature is 93.3 degC. The physical properties of the liquid are 977 kg/m^3, cp = 2.72 kJ/kg-K, k=0.346 W/m-K, and viscosity of 0.1 kg/m-s at 37.8 degC, and 0.0075 kg/m-s at 93.3degC. Calculate the heat loss using a carbon steel (k=44 W/m-K)
