Jul 15, 2003 A practical example of a limitation on tank geometry selection is low liquid level. A 48-in.-diameter tank with a 36-in. straight side and dished heads provides an example. Although extremely low liquid levels often are sought in batch processes, you must choose limits to keep the mixing intensity calculations valid.
Nov 01, 2016 Four baffles are installed around each agitator at 90-spacing along lines connecting the agitator shaft center with the four corners of a pit Figure 10.11. For a long rectangular pit with two or more agitators, the tank is divided into imaginary square compartments and a baffle is pointed at each corner either actual or imaginary.
tank, the size of the circulation paths is also large and the time taken to traverse them is long this, together with the regularity of liquid pumping at the impeller, inhibits rapid mixing.
Dec 06, 2002 13 Nov 02 1929. I have some problem to calculate the agitating system on my tank. I already known if the agitator position on top of tank, but I didnt know if it position on side of tank. How to calculate motor power reqd, size of shaft and everything that relation with the agitating system. Who will help me to solve my problem Thanks. Fuady.
Total volume of a cylinder shaped tank is the area, A, of the circular end times the length, l. A r 2 where r is the radius which is equal to 12 the diameter or d2. Therefore Vtank r 2 l Calculate the filled volume of a horizontal cylinder tank by first finding the area, A, of a circular segment and multiplying it by the length, l.
Our tank agitators are especially suitable for large storage tanks and oil tanks up to 120 m diameter. Their tasks are the effective mixing of the liquid tank content, the targeted elimination of sediment deposits and the maintenance of a constant temperature in the tank power range 555 kW.
Step-1 Power calculations and selection of motor For required power calculations, selection of the type of impeller is very important to achieve required agitation power. Selection of impeller is done based on application and type of flow. Flat paddle, turbine, anchor type,

Non-cylindrical mixing tanks are usually either rectangular, or horizontal tanks, and as previously mentioned these tanks usually do not require baffles unless the required level of agitation is high. These tanks are asymmetrical with respect to the mixer shaft and as a result are self-baffling for applications where the applied mixer power ...
