Question 4.14
A pitot-static tube is used to measure the air flowrate in a duct. A manometer
contains water is connected to the device to measure a pressure difference
between static and dynamic pressure.
If the flowrate in the pipe is 3.5 m/s and the diameter of the duct is 30
cm, determine the water column height in the manometer.
Sketch an appropriate diagram for the above system and label clearly
point 1, point 2 and the height of water column.
(a)
(b)
Take density of air = 1.2 kg/m3.
