This question was posed to me in an internship interview.

The query is from Classification of Orifice & Hydraulic Coefficients in division Fluid Dynamics of Fluid Mechanics

Answer 1

The correct option is (a) If the head of liquid is less than 5 times the depth of orifice

For explanation I would say: It is the correct parametric definition for ‘large orifice’.
