Question
Which one of the following equations to calculate the
discharge through an orifice? (a) 0 = 0 61 × 10 a √2 gh (b) 0 = 00186 LH3/2 (c)  0 = 0.16 × 10–3 a √2 gh (d)  0 = 00138 Hh/2Solution
Q represents the discharge rate, a is the area of the orifice, g is the acceleration due to gravity, and h is the head or height of the fluid above the orifice. This equation is derived from the principles of fluid mechanics and is commonly used to estimate the flow rate through an orifice.
