Question

The velocity of flow of liquid through an orifice at the bottom of a tank depends on the _________.

• A. height of the liquid above the orifice
• B. acceleration due to gravity
• C. area of the cross-section of orifice
• D. both a and b

Answer 1

The correct option is D both a and b

The velocity of flow of liquid through an orifice at the bottom of a tank depends on pressure at orifice which depends upon the density of liquid, acceleration due to gravity and height of liquid above orifice. It is independent of area of orifice.

So A and B have correct statements.
