A fluid flow through an orifice of an area 0.4 m2 with an actual discharge of 400 l/s. If the theoretical velocity of flow through the orifice 2 m/s, what is the coefficient of discharge?

Question

A fluid flow through an orifice of an area 0.4 m2 with an actual discharge of 400 l/s. If the theoretical velocity of flow through the orifice 2 m/s, what is the coefficient of discharge?

RRB Paper · Accepted Answer

The coefficient of discharge (Cd) is defined as: Cd = Qactual/Qtheoretical Qtheoretical = Area of orifice × velocity of flow Velocity of flow Vth = 2 m/s Area of orifice, a = 0.4 m2/s Qtheoretical = 2 × 0.4 = 0.8m3/s Actual discharge = 400 litre/sec = 400/1000 = 0.4 m3/sec coefficient of discharge, CD =  0.4/0.8 = 0.5
