A thin orifice plate inside a pipe causes a large drop in pressure between location 1 and location 2 equal to 145 kPa. Water flows at 500 gpm (gallons per minute). The diameter of the pipe is 10 cm and the diameter of the orifice in the plate is 6 cm. Use the control volume between location 1 and location 2. Compute the magnitude of the force on the orifice plate. Assume a constant density of 1000 kg/m3.
