Question

For Inlet diameter $>$ Outlet diameter the Velocity and pressure along the flow will be as

• A. Velocity decreases, pressure increases
• B. Velocity increases, pressure decreases
• C. Velocity constant, pressure decreases
• D. Velocity increases, pressure constant

Hint:

This configuration behaves exactly like a convergent nozzle.
In convergent nozzles:
Area $\downarrow$ $\implies$ Velocity $\uparrow$ $\implies$ Pressure $\downarrow$.
This is a standard application of Venturi principles.

Answer 1
