Selecting the Right Fan or Blower for Your Application
Sizing of fans and blowers is similar in process to that of pumps, where graphs are commonly used. The performance graph is usually a constantspeed plot with capacity on the X axis and a variety of performance factors on the Y axis. As part of the selection process, a graph of the system is also generated, with capacity as the X axis and head (energy loss in the system) on the Y axis.

Balancing Rotating Fixtures Turning Operations on a Lathe Formulas and Calculator
Manufacturing fixtures rotating at a high speed require balancing. Often it is assumed that the center of gravity of the work piece and fixture and of the counterbalancing masses are in the same plane; however, this is not usually the case. Counterbalancing masses are required in two separate planes to prevent excessive vibration or bearing loads at high speeds.

Counterbalancing Several Masses Located in a Single Plane Formulas and Calculator
Counterbalancing Several Masses Located in a Single Plane Formulas and Calculator In all balancing problems, the product of the counterbalancing mass (or weight) and its radius are calculated; it is thus necessary to select either the mass or the radius and then calculate the other value from the product of the two quantities.

Sphericity of Sphere Formulas and Calculator
Sphericity of a Sphere Formulas and Calculator Sphericity is, naturally, a measure of how spherical an object is. Defined by Wadell in 1932, the sphericity ψ of a particle is the ratio of the surface area of a sphere with the same volume as the given spherical particle to the surface area of the particle.
