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

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).
Impeller Tip Diameter - (Measured in Meter) - Impeller Tip Diameter is the distance of the tip from the center of the shaft.
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.

STEP 1: Convert Input(s) to Base Unit

RPM: 17000 --> No Conversion Required
Impeller Tip Diameter: 0.57 Meter --> 0.57 Meter No Conversion Required
Impeller Hub Diameter: 0.5 Meter --> 0.5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

U_t = pi*N/60*sqrt((D_t^2+D_h^2)/2) --> pi*17000/60*sqrt((0.57^2+0.5^2)/2)

Evaluating ... ...

U_t = 477.23105861135

STEP 3: Convert Result to Output's Unit

477.23105861135 Meter per Second --> No Conversion Required

FINAL ANSWER

477.23105861135 ≈ 477.2311 Meter per Second <-- Tip Velocity
