The pitot tube is used to measure
A. velocity at stagnation point
B. stagnation pressure
C. static pressure
D. dynamic pressure
Answer: Option B
Solution (By Examveda Team)
The tube for sensing the static pressure is known as static tube which surrounds the pitot tube that measures the stagnation pressure.This Question Belongs to Civil Engineering >> Hydraulics And Fluid Mechanics

A. 22.5 m/sec.
B. 33 m/sec.
C. 40 m/sec.
D. 90 m/sec.
A. the weight of the body
B. more than the weight of the body
C. less than the weight of the body
D. weight of the fluid displaced by the body
The difference of pressure between the inside and outside of a liquid drop is
A. $${\text{p}} = {\text{T}} \times {\text{r}}$$
B. $${\text{p}} = \frac{{\text{T}}}{{\text{r}}}$$
C. $${\text{p}} = \frac{{\text{T}}}{{2{\text{r}}}}$$
D. $${\text{p}} = \frac{{2{\text{T}}}}{{\text{r}}}$$
A. cannot be subjected to shear forces
B. always expands until it fills any container
C. has the same shear stress.at a point regardless of its motion
D. cannot remain at rest under action of any shear force
Pitot tube measures only stagnation pressure while pitot static tube measures both static and stagnation pressures collectively known as Dynamic pressure.
@shaikh omer
Velocity at stagnation point already zero.
So pitot tube used to measure velocity at static point and to measure stagnation pressure
In this question, velocity at a stagnation point is given in the option 1, which is zero. So here the answer will be stagnation pressure.
Velocity of flow
Pitote tube is used to find the velocity.. . Answer A is right
