Power Consumption in Agitated Vessel

Power Consumption in Agitated Vessel Many processing operations depend for their success on the effective agitation and mixing of fluids. Hence it is of great importance to study these agitated vessels. Liquids are most often agitated in some kind of tank or vessel usually cylindrical in form and with a vertical axis. Tank bottom is rounded to eliminate regions into which the fluid currents would not penetrate. In the present set-up agitation is done with the help of stirrer. A DC motor is coupled 10 SS Impeller and SS Shaft. Digital Voltmeter and Digital Ammeter can vary the speed of agitators with the help of Thyristor controlled and power consumption is measured. Four replaceable baffles are provided to prevent swirling. One propeller and one turbine are provided which are interchangeable. Drain valve is also provided at the bottom. The whole set-up is mounted on a rigid MS frame structure. Range of Experiments:  To plot Power number Vs Reynolds number for the given set of impeller with baffled/ unbaffled mixing.
