Velocity Measurements
Data & Calculations
• The tube is not without its errors while simple.
• The most important likelihood for error arises from its dependence
on alignment with the fluid flow direction for the correctness of the
measured velocity.
"Yaw Angle Dependence"
• For an established flow in the open channel flume the fluid velocity
(Ah on the manometer) will change at different directions of the
pitot tube (0°, 30°, 45°).

Questions and Conclusions
• What trend did you notice in the yaw angle-induced error?
• What trend did you notice in the velocity at different
depths?
Describe and explain the reaction of the static and stagnant
pressure manometer. Why should this reaction have been
predicted?
