Answer:
C
Explanation:
Pitot tube:
Pitot tube is a device which is used to measure the velocity of flow by measuring pressure difference between the points.
As we know that stagnation pressure is the summation of dynamic and static pressure.
Stagnation pressure = Static pressure + Dynamic pressure
So
Dynamic pressure = Stagnation pressure - Static pressure
We know that dynamic pressure
On the other hand Pitot tube measure the dynamic pressure.
So option C is correct.
Answer:
all are zero.
Explanation:
We know that if flow is possible then it will satisfy the below equation
Where u is the velocity of flow in the x-direction ,v is the velocity of flow in the y-direction and w is the velocity of flow in z-direction.
And velocity potential function given as follows
Rotationality of fluid is given by
So now putting value in the above equations ,we will find
So =0
Like this all all are zero.
That is why velocity potential flow is irroational flow.
