Related Calculations. Use the similarity laws to extend or change the data obtained from centrifugal-pump characteristic curves. These laws are also useful in field calculations when the pump head, capacity, speed, or impeller diameter is changed. [Pg.204]

For a given centrifugal pump operating at a constant speed, the flow rate through the pump is dependent upon the differential pressure or head developed by the pump. The lower the pump head, the higher the flow rate. A vendor manual for a specific pump usually contains a curve of pump flow rate versus pump head called a pump characteristic curve. After a pump is installed in a system, it is usually tested to ensure that the flow rate and head of the pump are within the required specifications. A typical centrifugal pump characteristic curve is shown in Figure 21.3. [Pg.396]

In the present study, experiments were conducted to determine the individual effects of solid properties (particle size, solids specific gravity) and solids concentration by weight, as well as tip clearance effects on an open impeller centrifugal pump characteristics. Tip clearance is varied from 1.25 mm to 8 mm over the experiments and maximum particle size was approximately 2.4 mm. Test results have shown that, slurry characteristics and running tip clearance have a considerable impact on the pump performance. These effects, therefore, must be taken into account for piunp design considerations and selection. [Pg.499]

In order to study the effects of the suspended solids on the centrifugal pump characteristics (i) beach sand, (ii) perlite, (iii) casting sand were utilised in the experiments. The physical properties of the materials are shown in Table 1. The particle size distributions of the materials were determined by sieve analysis. The weighted mean diameter (d v) of different materials was calculated and the mass median diameter (dso) was obtained from cumulative percentage undersize-particle diameter plot. [Pg.501]
