Torricelli Orifice Model
Flow Formula (Q)
Q = Cd × Area × √(2gH)
Ideal Velocity (V)
Vi = √(2gH)
Actual Velocity (Va)
Va = Cv × Vi (Cv ≈ 0.97)
Kinetic Power (P)
P = ρ × Q × g × H
Discharge coefficient (Cd) combines the effects of contraction (Cc) and velocity loss (Cv).
Maximum jet range is achieved when the orifice is centered vertically in the container height.
