A diaphragm is installed in the water line to limit water flow. The excess pressures in the pipe before and after the diaphragm are constant and equal to p1 = 6.37•104 Pa and p2 = 2.05•104 Pa, respectively. Pipe diameter D = 0.076 m. Determine the required diameter of the diaphragm hole d so that the flow rate in the line is Q = 0.0059 m3/s.
