How to calculate supersonic velocity using a pitot tube

(i) Assume that the two pressures are measured separately using individual pressure gages: pr 102 t 1 kPa (P 0.95, 0 bias), pi 95 t 1 kPa (P 0.95, 0 bias). The density is estimated to be 680 50 kg/m3 (P 0.95, 0 bias). The estimation of the velocity is given by the equation in which vi is the local velocity at location 1, pthe density of the liquid, pr the total pressure measured by the tube, and pi the static pressure at location 1. Estimate the uncertainty for vi gage: pr p Which arrangement, (a) or (b), is preferable and why?ДЄ pitot tube is used to measure the velocity of gasoline flowing in a pipe. a parameter study of the problem by making Euler computations of supersonic flow over a pitot tube when white acoustic noise is introduced at the inflow.

Estimate the uncertainty for v ( Assume that the pressure difference pr-pi is measured using a single differential pressure 7t 1 kPa (P 0.95, 0 bias). compressible flow is derived from the Rayleigh Supersonic Pitot equation. (i) Assume that the two pressures are measured separately using individual pressure gages: pr 102 t 1 kPa (P 0.95, 0 bias), pi 95 t 1 kPa (P 0.95, 0 bias). Unlike most units of measure, with Mach the number comes after the unit. Calculate the Mach number of the flow in the test section. A static pressure measurement (from a pressure tap on the sidewall of the test section) yields 0.1 atm. Pitot is attached to the small tube in the middle about 15cm away from where the small tube starts.

Experiment Setup: Air pump blowing air at an unknown constant velocity into a horizontal large tube which narrows down to a tube with a smaller diameter (venturi). The density is estimated to be 680 50 kg/m3 (P 0.95, 0 bias). Solutions for Chapter 8 Problem 16P: In the test section of a supersonic wind tunnel, a Pitot tube in the flow reads a pressure of 1.13 atm. The pressure measured in pitot is in mmH2O and atmospheric pressure is 763.25 mmHg. A pitot tube is used to measure the velocity of gasoline flowing in a pipe.
