Impeller Outlet Diameter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Impeller Tip Diameter = (60*Tip Velocity)/(pi*RPM)
D_t = (60*U_t)/(pi*N)
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Impeller Tip Diameter - (Measured in Meter) - Impeller Tip Diameter is the distance of the tip from the center of the shaft.
Tip Velocity - (Measured in Meter per Second) - Tip Velocity is blade speed at the tip of the compressor.
RPM - RPM is the number of turns of the object divided by time, specified as revolutions per minute (rpm).

STEP 1: Convert Input(s) to Base Unit

Tip Velocity: 485 Meter per Second --> 485 Meter per Second No Conversion Required
RPM: 17000 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D_t = (60*U_t)/(pi*N) --> (60*485)/(pi*17000)

Evaluating ... ...

D_t = 0.544871628702842

STEP 3: Convert Result to Output's Unit

0.544871628702842 Meter --> No Conversion Required

FINAL ANSWER

0.544871628702842 ≈ 0.544872 Meter <-- Impeller Tip Diameter
