Airspeed Measurement by Venturi Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity at Point 1 = sqrt((2*(Pressure at Point 1-Pressure at Point 2))/(Density*(Contraction Ratio^2-1)))
V₁ = sqrt((2*(P₁-P₂))/(ρ₀*(A_lift^2-1)))
This formula uses 1 Functions, 5 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

Velocity at Point 1 - (Measured in Meter per Second) - Velocity at Point 1 is the velocity of fluid passing through point 1 in flow.
Pressure at Point 1 - (Measured in Pascal) - Pressure at Point 1 is the pressure on streamline at a given point in the flow.
Pressure at Point 2 - (Measured in Pascal) - Pressure at Point 2 is the pressure on streamline at a given point in the flow.
Density - (Measured in Kilogram per Cubic Meter) - The Density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object.
Contraction Ratio - Contraction ratio is the ratio of inlet area or reservoir area to the test section area or throat area of a duct.

STEP 1: Convert Input(s) to Base Unit

Pressure at Point 1: 9800 Pascal --> 9800 Pascal No Conversion Required
Pressure at Point 2: 9630.609 Pascal --> 9630.609 Pascal No Conversion Required
Density: 997 Kilogram per Cubic Meter --> 997 Kilogram per Cubic Meter No Conversion Required
Contraction Ratio: 2.1 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V₁ = sqrt((2*(P₁-P₂))/(ρ₀*(A_lift^2-1))) --> sqrt((2*(9800-9630.609))/(997*(2.1^2-1)))

Evaluating ... ...

V₁ = 0.315671515398847

STEP 3: Convert Result to Output's Unit

0.315671515398847 Meter per Second --> No Conversion Required

FINAL ANSWER

0.315671515398847 ≈ 0.315672 Meter per Second <-- Velocity at Point 1
