Application of Pitot Tubes in
Daily Life
• Measuring air speed and the speed of motion of the aircraft.
• Application of the aircraft altimeter. Altimeter used to measure the height of a point from the surface of the sea.
•Determine the amount of coolant that was in the room to tell at a hotel.•Determining the wind speed in the tunnel.•measuring the speed of air or gas in the pipe is closed.
Application Application of pitot tube
equations can be applied to the aircraft altimeter.An Altimeter is used to measure the height of a point from the surface of the sea and to read the reading speed relative speed of aircraft
Example Problem
Known:ρ = 3,4 kg/m3
Ρ’ = 13600 kg/m3
g = 10 m/s2 h = 2 cm = 2 × 10-2 m
Asked:v = ?
Answer:
In the pitot tube was discharged by gases (ρ = 3,4 kg/m3) so the difference of mercury height at manometer is 2 cm. If the gravity is 10 m/s2 and density of mercury is 13600 kg/m3 , determine velocity of gases flow in the pitot tube!

Conclusion
Pitot tube is the instrument that discovered by Henri Pitot from France in the early 1700s. This tool usually used to measure air speed and motion in the plane.
