Diameter of suction pipe Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Suction Pipe of Pump = sqrt((4*Actual Discharge at Centrifugal Pump Outlet)/(pi*Velocity in Suction Pipe))
D_s = sqrt((4*Q)/(pi*V_s))
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Diameter of Suction Pipe of Pump - (Measured in Meter) - Diameter of suction pipe of pump is the diameter of cross-section of the circular pipe at the suction side of the pump.
Actual Discharge at Centrifugal Pump Outlet - (Measured in Cubic Meter per Second) - Actual discharge at centrifugal pump outlet is the actual amount of the liquid outflow from the outlet of the centrifugal pump.
Velocity in Suction Pipe - (Measured in Meter per Second) - Velocity in Suction Pipe is the velocity of liquid in suction pipe.

STEP 1: Convert Input(s) to Base Unit

Actual Discharge at Centrifugal Pump Outlet: 0.056 Cubic Meter per Second --> 0.056 Cubic Meter per Second No Conversion Required
Velocity in Suction Pipe: 2.1 Meter per Second --> 2.1 Meter per Second No Conversion Required

What is the general value of vane efficiency in centrifugal pumps?

It has been observed through experiments that as the number of vanes is increased the value of ε increases and approaches unity. The value of ε, in addition to number of vanes, depends on the shape of the vane and the outlet vane angle. In general, for radial flow pumps the value of ε varies from 0.6 to 0.8 as the number of vanes is increased from 4 to 12. However, for impeller with vanes more than 24 the value of ε may be taken as unity, unless mentioned otherwise.
