Airspeed Measurement by Pitot Tube Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity at Point 1 = sqrt((2*(Total Pressure-Static Pressure at Point 1))/(Density))
V₁ = sqrt((2*(P₀-P_{1 static}))/(ρ₀))
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

Velocity at Point 1 - (Measured in Meter per Second) - Velocity at Point 1 is the velocity of fluid passing through point 1 in flow.
Total Pressure - (Measured in Pascal) - Total Pressure denotes the sum of static pressure and dynamic pressure in a fluid flow.
Static Pressure at Point 1 - (Measured in Pascal) - Static pressure at Point 1 refers to the pressure exerted by a fluid at a specific location in a system, where the fluid is not in motion or has zero velocity.
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.

STEP 1: Convert Input(s) to Base Unit

Total Pressure: 61710 Pascal --> 61710 Pascal No Conversion Required
Static Pressure at Point 1: 61660 Pascal --> 61660 Pascal No Conversion Required

Where are Pitot tubes and Static Pressure taps are mounted on the moderns airplanes?

Modern airplanes have a pitot tube mounted at some location on the fuselage. The position of static pressure tap on the surface of the fuselage is critical; it must be located in the region where the surface pressure on the fuselage is equal to the free stream that is the location where the pressure coefficient is zero.
