Heat Transfer in Agitated Vessel Manufacturer,Supplier and Exporter in India
Product Code : EL-HTL-10048
Jlab Export is a leading Heat Transfer in Agitated Vessel Manufacturer,and suppliers in India
Heat Transfer in Agitated Vessel (code EL-HTL-10048) is a stirred-vessel rig in which water in an insulated vessel of about 20 litres, heated by an electric heater at the bottom, gives up heat to cold water circulating through a helical copper coil. A motorised agitator at the centre of the coil stirs the vessel, so the heat transfer coefficient can be measured at different agitator speeds. This stirred-vessel unit is manufactured by JLab in Ambala, India.

Overall Coefficient of the Coil
The heat taken up in the coil is Q = ṁ cp (To − Ti), where ṁ is the mass flow of cooling water, which runs at 4–5 L/min, and Ti and To are its inlet and outlet temperatures. Because the agitator keeps the vessel water at one temperature Tv, the driving difference is the log mean, ΔTlm = (To − Ti)/ln[(Tv − Ti)/(Tv − To)], and the overall coefficient follows as U = Q/(A ΔTlm), with A the outer surface of the 8-turn coil. U combines the film on the vessel side, the copper wall and the film inside the tube.
Effect of Agitator Speed
Stirring thins the layer of slow-moving water on the outside of the coil, so the vessel-side film coefficient, and with it U, rises as the controller raises the agitator speed. Repeating the test at several speeds gives the curve of U against speed. Vessel-side coefficients in stirred tanks are usually correlated against an agitator Reynolds number, ρND²/μ, built from the 150 mm agitator diameter D and its speed N.
