Pumps performance, dimensionless

Not only is the type of flow related to the impeller Reynolds number, but also such process performance characteristics as mixing time, impeller pumping rate, impeller power consumption, and heat- and mass-transfer coefficients can be correlated with this dimensionless group. [Pg.1629]

Figure 7.2. Performance curves in dimensional and dimensionless forms (a) Data of a pump with a specific diameter and rotation speed, (b) Dimensionless performance curves of all pumps geometrically similar to (a). The dashed lines identify the condition of peak efficiency. (After Daugherty and Franzini, Fluid Mechanics with Engineering Applications, McGraw-Hill, New York, 1957). Figure 7.2.

It is required to clarify 8 L/s of the suspension in Example 10.4 using hydrocyclones of Rietma s optimum geometry. The concentration of the suspension is 15% by volume and its density has been measured as 1250 kg/m. The maximum pumping capacity available for performing the separation is 315 kPa. Find out the optimum cyclone diameter and the number of units, if necessary, in order to obtain a cut size of 8 pm. Small-scale experimentation has determined values of some dimensionless relationships as follows Stkjg Eu = 0.0625, and Eu = 720. The density of the suspended solids is 2800 kg/m. ... [Pg.422]
