Q.

The discharge through a small rectangular orifice is given by (where Cd = Coefficient of discharge for the orifice, a = Cross-sectional area of the orifice, h = Height of the liquid above the centre of the orifice)

  • AQ = Cd × a × 2gh
  • BQ = (2/3). Cd × a × h
  • CQ = (Cd × a)/√(2gh)
  • DQ = (3Cd × a)/√(2h)
Correct Answer : (A)

Q = Cd × a × 2gh
