A jacketted-agitated vessel, fitted with a turbine agitator, is used for heating a water stream from 10°C to 54°C. The average heat transfer coefficient for water at the vessel’s inner-wall can be estimated from Nu = 0.76Re^2/3Pr^1/3. Saturated steam at 100°C condenses in the jacket, for which the average heat transfer coefficient in kW/m²·K is h_o = 13.1(T_g - T_w)^-0.25. The vessel dimensions are D_t = 0.6 m, H = 0.6 m and D_a = 0.2 m. The agitator speed is 60 rpm. Calculate the mass rate of water that can be heated in this agitated vessel steadily.
