SSC SSC JE Civil 2025 Mock Test Series (Paper 1 & Paper 2) Fluid Mechanics Flow Measurement Orificemeter
A fluid jet discharging from a 4 cm diameter orifice has a diameter 3 cm at its vena contracta. If the coefficient of velocity is 0.98, the coefficient of discharge for the orifice will be
1
0.98 × (0.75)2
2
(0.75)2 / 0.98
3
0.98 × (1.33)2
4
0.98 / (0.75)2
