An orifice meter, having orifice diameter of d is placed in a water pipeline having flow rate, . The ratio of orifice diameter to pipe diameter is 0.6. The contraction coefficient is also 0.6. The density of water is 1000 kg/m3. If the pressure drop across the orifice plate is 43.5kPa, the discharge co-efficient of the orifice meter at this flow Reynolds number is _________.
Answer: 0.29 to 0.33
