An orifice meter with orifice diameter 10cm is inserted in a pipe of 20cm diameter. The pressure gauges fitted up stream and downstream of the orifice meter gives reading of 19.62N/cm2 and 9.81N/cm2 respectively Co-efficent of discharge for the orifice meter is given as 0.6. Find the discharge of water through pipe.
