STEP 0: Pre-Calculation Summary

Formula Used

Tip Velocity = pi*(2*Mean Diameter of Impeller^2-Impeller Hub Diameter^2)^0.5*RPM/60
U_t = pi*(2*D_m^2-D_h^2)^0.5*N/60
This formula uses 1 Constants, 4 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Tip Velocity - (Measured in Meter per Second) - Tip Velocity is blade speed at the tip of the compressor.
Mean Diameter of Impeller - (Measured in Meter) - Mean Diameter of Impeller is the diameter that divides the total annular area into two equal parts.
Impeller Hub Diameter - (Measured in Meter) - Impeller Hub Diameter is the distance of the hub (where the blade roots are mounted) from the center of the shaft.
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

Mean Diameter of Impeller: 0.53 Meter --> 0.53 Meter No Conversion Required
Impeller Hub Diameter: 0.5 Meter --> 0.5 Meter No Conversion Required
RPM: 17000 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

U_t = pi*(2*D_m^2-D_h^2)^0.5*N/60 --> pi*(2*0.53^2-0.5^2)^0.5*17000/60

Evaluating ... ...

U_t = 497.033429040923

STEP 3: Convert Result to Output's Unit

497.033429040923 Meter per Second --> No Conversion Required

FINAL ANSWER

497.033429040923 ≈ 497.0334 Meter per Second <-- Tip Velocity
