## Discharge of a pump given specific speed Solution

STEP 0: Pre-Calculation Summary
Formula Used
discharge = sqrt(Specific speed of a pump*(Head^(3/4))/Speed)
Q = sqrt(Ns*(H^(3/4))/N)
This formula uses 1 Functions, 3 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Specific speed of a pump - Specific speed of a pump is the speed of machines discharging 1m3/sec under 1m head. (Measured in Revolution per Minute)
Head - Head is defined as the height of water columns (Measured in Meter)
Speed- Speed of a machine/body in rpm.
STEP 1: Convert Input(s) to Base Unit
Specific speed of a pump: 100 Revolution per Minute --> 10.4719755114327 Radian per Second (Check conversion here)
Head: 1 Meter --> 1 Meter No Conversion Required
Speed: 100 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Q = sqrt(Ns*(H^(3/4))/N) --> sqrt(10.4719755114327*(1^(3/4))/100)
Evaluating ... ...
Q = 0.323604318751044
STEP 3: Convert Result to Output's Unit
0.323604318751044 Meter³ per Second --> No Conversion Required
0.323604318751044 Meter³ per Second <-- Discharge
(Calculation completed in 00.009 seconds)

### Discharge of a pump given specific speed Formula

discharge = sqrt(Specific speed of a pump*(Head^(3/4))/Speed)
Q = sqrt(Ns*(H^(3/4))/N)

## What is specific speed of a pump?

The specific speed of a pump is defined as the speed of a geometrically similar pump which would deliver unit quantity (one cubic meter of liquid per second) against a unit head(one meter). It is denoted by Ns. The specific speed is a characteristic of pumps which can be used as a basis for comparing the performance of different pumps.

## How to Calculate Discharge of a pump given specific speed?

Discharge of a pump given specific speed calculator uses discharge = sqrt(Specific speed of a pump*(Head^(3/4))/Speed) to calculate the Discharge, The Discharge of a pump given specific speed formula is defined as the square root of ratio of product of specific speed and head raised to power of 3/4 to the speed of pump. Discharge and is denoted by Q symbol.
