Outlet Diameter of Impeller using Speed Ratio, Manometric Head and Impeller Speed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Centrifugal Pump Impeller at Outlet = (84.6*Speed Ratio Centrifugal Pump*sqrt(Manometric Head of Centrifugal Pump))/Angular Velocity
D₂ = (84.6*K_u*sqrt(H_m))/ω
This formula uses 1 Functions, 4 Variables

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 Centrifugal Pump Impeller at Outlet - (Measured in Meter) - Diameter of centrifugal pump impeller at outlet is the diameter of the impeller at the outlet of the centrifugal pump.
Speed Ratio Centrifugal Pump - Speed ratio centrifugal pump is the ratio of the peripheral speed of impeller at exit to the theoretical velocity of the jet corresponding to manometric head.
Manometric Head of Centrifugal Pump - (Measured in Meter) - The Manometric Head of Centrifugal Pump is the head against which the centrifugal pump has to work.
Angular Velocity - (Measured in Revolution per Minute) - The Angular Velocity of Centrifugal Pump refers to how fast the pump impeller rotates.

STEP 1: Convert Input(s) to Base Unit

Speed Ratio Centrifugal Pump: 0.85 --> No Conversion Required
Manometric Head of Centrifugal Pump: 25.3 Meter --> 25.3 Meter No Conversion Required
Angular Velocity: 179.07 Radian per Second --> 1709.99253965502 Revolution per Minute (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D₂ = (84.6*K_u*sqrt(H_m))/ω --> (84.6*0.85*sqrt(25.3))/1709.99253965502

Evaluating ... ...

D₂ = 0.211521897467202

STEP 3: Convert Result to Output's Unit

0.211521897467202 Meter --> No Conversion Required

FINAL ANSWER

0.211521897467202 ≈ 0.211522 Meter <-- Diameter of Centrifugal Pump Impeller at Outlet

(Calculation completed in 00.004 seconds)
