Pitot Tubes are devices that are used to determine the velocity of a fluid, or an object moving through a fluid. The Pitot tube does this by determining the difference in pressure between the static pressure and stagnation pressure of the fluid. Refer to equation 1.

**(Eq 1) ** $v=\sqrt{2\frac{P_3-P_4}{ρ}}$

v = velocity

P = Pressure

ρ = Density
