what happens to fluid flow and pressure when it passes through an orifice?\na) flow increases and pressure increases.\nb) flow decreases and pressure increases.\nc) flow stays the same and pressure decreases.\nd) flow and pressure decrease.

Answer

Brief Explanations:

According to the principle of continuity and Bernoulli's principle in fluid - dynamics, when a fluid passes through an orifice, the cross - sectional area of the flow path decreases. To maintain the same volumetric flow rate (continuity equation), the velocity of the fluid increases. And according to Bernoulli's equation, as the velocity of the fluid increases, the pressure decreases. So the flow rate (volumetric flow rate) stays the same and the pressure decreases.

Answer:

C. Flow stays the same and pressure decreases.
