A venturimeter with a throat diameter of 7.5 cm in a 15 cm diameter pipe. The pressure at entrance to the meter is 70 kpa and it is desired that the pressure at any point should not fall below 2.5m of water absolute. Determine the maximum flow rate of water through the meter. Take Cd=0.97 and atmosphere pressure as 100 kpa. (Hint, the pressure at the throat will be minimum. Hence p2/pg=2.5 m (abs).
