Question

In conditions of pumping performance, how have to engineers determined use of radial flow pumps and axial flow pumps?

Answer

Exact speed is usually defined for a pump operating at its utmost efficiency. In command to minimize price of future operation, it is attractive to operate pumps as close to maximum efficiency point as possible. Specific speed for radial flow pumps is comparatively small at what time compared with that of axial flow pumps. This implies that radial flow pumps be inclined to give higher head with lower discharge as axial flow pumps tend to give higher discharge with lower head.
