ChatHydraulic Pump Power. The ideal hydraulic power to drive a pump depends on. the mass flow rate the; liquid density; the differential height either it is the static lift from one height to an other or the total head loss component of the system and can be calculated like. P h(kW) = q ρ g h /
ChatAgitator. An Agitator is a machine used in a tank for mixing various process media together. Media include all liquid types, gases solids (such as salts, powders, granules etc). In summary, it works by rotating an impeller to impart energy to the media which interact and mix. The components of an agitator in general are the motor gearbox
ChatThe power input P to an impeller of diameter D driven at a rotational speed N in a fluid of density ρ and viscosity η can be expressed in terms of a dimensionless Power number, P/(N 3 D 5 ρ). This is a form of drag coefficient and is a function of the mixing Reynolds number /(ND 2 ρ/η). For a given pattern of impeller the Po vs. Re function is always of the same form.

Chat4/5/2014· This is because of the well known relationship, power = flow*head. (Agitators produce orders of magnitude lower head, by virtue of not having to pump through a pipe.) Similarly, to achieve equal blend time to that produced by an agitator, a pump would require about 100 150 times as much power. Based on such huge differences in power required

ChatMultiple or dual impellers are widely implemented in stirred contactors used in various biological processes like fermentation, water treatment, and pharmaceutical production. The spacing between impellers is considered as a crucial factor in designing of these types of contactors resulting in variation of oxygen mass transfer, mixing time, or power consumption for such biological system.

Chat13/5/2019· This blog discusses the mechanical power associated with a mixing impeller in a stirred tank. The power associated with an impeller is related to four primary factors: Impeller geometry; Impeller diameter; Impeller rotational speed; Fluid properties of the material being mixed; The relationship of these components can be expressed in the following equation:
ChatNon 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
