How does a pitot tube utilize the principles of Bernoulli's equation to measure fluid flow velocity?
A pitot tube uses Bernoulli's equation to measure fluid flow velocity by comparing the pressure difference between the stagnation point and the dynamic pressure of the fluid. This difference in pressure is used to calculate the velocity of the fluid flowing past the pitot tube.
Difference between uniform and non-uniform flow of fluid?
Uniform flow occurs when the fluid velocity and properties are constant throughout the flow field, while non-uniform flow has varying velocity and properties across the flow field. In uniform flow, streamlines are parallel and the flow is steady, whereas in non-uniform flow, streamlines may converge or diverge and the flow can be unsteady.
Why do fluids flow faster near the center of pipes and tubes than at the edges?
Fluid flow is typically faster near the center of pipes and tubes due to lower frictional losses compared to the edges. The no-slip condition at the walls of the pipe causes the fluid velocity to be slower at the edges due to viscous drag, resulting in a velocity gradient across the pipe cross-section. This varying velocity profile is known as a parabolic flow profile.
What is the relationship between flow velocity and area?
Flow velocity and area are inversely related in a fluid system. When the area decreases, the flow velocity increases, and vice versa, according to the principle of continuity, which states that the product of cross-sectional area and flow velocity remains constant in an enclosed system with steady flow.
What is the difference between Diffuser and nozzle?
A diffuser is a device that reduces the velocity of a fluid and increases its pressure, often by expanding the flow area. A nozzle, on the other hand, is a device that accelerates the flow of a fluid by constricting the flow area, which increases its velocity. In simpler terms, a diffuser slows down fluid flow while a nozzle speeds it up.

Difference between turbulent flow and streamlined flow?
Streamline flow:The flow of a fluid is said to be streamline (also known as steady flow or laminar flow), if every particle of the fluid follows exactly the path of its preceding particle and has the same velocity as that of its preceding particle when crossing a fixed point of reference.Turbulent flow:The flow of a fluid is said to be turbulent or disorderly, if its velocity is greater than its critical velocity. Critical velocity of a fluid is that velocity up to which the fluid flow is streamlined and above which its flow becomes turbulent. When the velocity of a fluid exceeds the critical velocity, the paths and velocities of the fluid particles begin to change continuously and haphazardly. The flow loses all its orderliness and is called turbulent flow.

What is the definition of velocity lag?
In a flow of matter, such as in a rocket, velocity lag is the speed difference between the flowing gas particles and solid/liquid particles. Any amount of velocity lag slows down the overall force and speed of the matter flow.
What is the relationship between river depth and width and velocity of flow?
Manning equation if the hydraulic radius decreases then the velocity decreases
What is the relationship between velocity gradient and fluid flow in a dynamic system?
The velocity gradient in a fluid flow system refers to the change in velocity across different points in the fluid. In a dynamic system, the velocity gradient is directly related to the fluid flow rate. A higher velocity gradient indicates a faster flow rate, while a lower velocity gradient indicates a slower flow rate. This relationship helps to understand how the fluid moves and behaves within the system.
What is the basic Difference between flow chart and pseudo-code?

What is velocity gradient?
The difference in velocity between adjacent layers of the fluid is known as a velocity gradient and is given by v/x, where v is the velocity difference and x is the distance between the layers. To keep one layer of fluid moving at a greater velocity than the adjacent layer, a force F is necessary, resulting in a shearing stress F/A, where A is the area of the surface in contact with the layer being moved.
