An airplane is in level flight at low altitude, so that atmospheric pressure and densities are 1 atm and 1 kg/m3 , respectively. There is a Pitot tube attached to the airplane, so that air entering the tube stagnates at the rear of the tube. The stagnation pressure is measured to be 2.00 x 105 Pa. What is the speed of the airplane?

An airplane is in level flight at low altitude, so that atmospheric pressure and densities are 1 atm and 1 kg/m3 , respectively. There is a Pitot tube attached to the airplane, so that air entering the tube stagnates at the rear of the tube. The stagnation pressure is measured to be 2.00 x 105 Pa. What is the speed of the airplane? (The laser is there to detect particulates in the air which might interfere with the operation of the probe.) Explain all steps
