Explanation: These include all the impellors in which the blade makes an angle of less than 900 with the plane of the rotation.

Explanation: These impellors have blades which are parallel to the axis of shaft, or have an angle equals to 180 degrees with the shaft.

Explanation: Speeds up to 1000 Hz are used to give accelerations 50,000 times the gravitational acceleration, the basket rotates at 15,000 rpm.

Explanation: For a given feed rate to the centrifuge, the degree of separation depends upon the thickness of liquid layer at the walls of the baskets.

Explanation: Mixing involves the mixing of gases, liquid or solids in any possible combination of two or more constituents.

Explanation: Mixing is accomplished by the rotation action of the impeller in the continuous fluid, also it can be done by agitation but is not economical.

Explanation: Impellors may be roughly be dived into two broad classes mainly axial and radial flow type of impellors, it depends upon angle they make.

Explanation: For defining the two phase systems, it is effective saturation Se that is commonly used, S¬e is used defined as the ratio of void containing wetting fluid and voids of both fluid.

Explanation: As Se = 2.5/8.5 = 0.294.

Explanation: If the radius of the basket is decreased by 50% then the revolutions per minute are doubled, than the linear speed of basket.
