Question: The thin-plate orifice in Fig P3.85 causes a large pressure drop. For 20°C water flow at 500 gal/min, with pipe D 10 cm and orifice

The thin-plate orifice in Fig P3.85 causes a large pressure drop. For 20°C water flow at 500 gal/min, with pipe D 10 cm and orifice d 6 cm, p1 −p2 ≈145 kPa, if the wall friction is negligible, estimate the force of the water on the orifice plate.
