Impeller power Solution

Follow our step by step solution on how to calculate Impeller power?

FIRST Step Consider the formula

IP = \frac{w \cdot Q \cdot V w2 \cdot u 2}{1000 \cdot [g]}

Next Step Substitute values of Variables

∴

IP = \frac{9.81kN/m³ \cdot 0.056m³/s \cdot 16m/s \cdot 19m/s}{1000 \cdot [g]}

Next Step Substitute values of Constants

∴

IP = \frac{9.81kN/m³ \cdot 0.056m³/s \cdot 16m/s \cdot 19m/s}{1000 \cdot 9.8066m/s²}

Next Step Convert Units

∴

IP = \frac{9810N/m³ \cdot 0.056m³/s \cdot 16m/s \cdot 19m/s}{1000 \cdot 9.8066m/s²}

Next Step Prepare to Evaluate

∴

IP = \frac{9810 \cdot 0.056 \cdot 16 \cdot 19}{1000 \cdot 9.8066}

Next Step Evaluate

∴

IP = 17029.8154823513W

Next Step Convert to Output's Unit

∴

IP = 17.0298154823513kW

LAST Step Rounding Answer

∴

IP = 17.0298kW

How to Evaluate Impeller power?

Impeller power evaluator uses Impeller Power of Centrifugal Pump = (Specific Weight of Fluid in Pump*Actual Discharge at Centrifugal Pump Outlet*Velocity of Whirl at Outlet*Tangential Velocity of Impeller at Outlet)/(1000*[g]) to evaluate the Impeller Power of Centrifugal Pump, The Impeller power formula is defined as the ratio of product of specific weight, discharge, whirl velocity and tangential velocity at outlet to the product of 1000 times acceleration due to gravity. Impeller Power of Centrifugal Pump is denoted by IP symbol.

How to evaluate Impeller power using this online evaluator? To use this online evaluator for Impeller power, enter Specific Weight of Fluid in Pump (w), Actual Discharge at Centrifugal Pump Outlet (Q), Velocity of Whirl at Outlet (V_w2) & Tangential Velocity of Impeller at Outlet (u₂) and hit the calculate button.

FAQs on Impeller power

What is the formula to find Impeller power?

The formula of Impeller power is expressed as Impeller Power of Centrifugal Pump = (Specific Weight of Fluid in Pump*Actual Discharge at Centrifugal Pump Outlet*Velocity of Whirl at Outlet*Tangential Velocity of Impeller at Outlet)/(1000*[g]). Here is an example- 0.01703 = (9810*0.056*16*19)/(1000*[g]).

How to calculate Impeller power?

With Specific Weight of Fluid in Pump (w), Actual Discharge at Centrifugal Pump Outlet (Q), Velocity of Whirl at Outlet (V_w2) & Tangential Velocity of Impeller at Outlet (u₂) we can find Impeller power using the formula - Impeller Power of Centrifugal Pump = (Specific Weight of Fluid in Pump*Actual Discharge at Centrifugal Pump Outlet*Velocity of Whirl at Outlet*Tangential Velocity of Impeller at Outlet)/(1000*[g]). This formula also uses Gravitational acceleration on Earth constant(s).
