How do you find fluid velocity using a Pitot tube?
Diving in to the components of FLUIDS (figuratively of course) can get quite complex and even more so when we start to dive in to the weeds of fluid flow measurement.
But it doesn’t need to be, in this video, we dive in to an FE Exam Practice Problem in the subject of FLUID MECHANICS, specifically revolving around defining the FLUID VELOCITY using a PITOT TUBE.
Key Definition
What is a PITOT TUBE?
A PITOT TUBE is a pressure measurement instrument used to measure fluid flow velocity.
As engineers, we see PITOT TUBES being used to determine the airspeed of an aircraft, water speed of a boat, and to measure liquid, air and gas flow velocities.
In this problem, we see a PITOT TUBE being used to measure the local flow velocity at a given point in the flow stream.
The basic PITOT TUBE consists of a tube pointing directly into the fluid flow. As this tube contains fluid, a pressure can be measured; the moving fluid is brought to rest as there is no outlet to allow flow to continue.
This pressure is the stagnation pressure of the fluid, also known as the total pressure or (particularly in aviation) the pitot pressure.
Check out the video and see how we can go about solving this type of problem in the most efficient manner.
