A venturimeter is installed in 200mm line to measure the flow rate of water. The manometer used to measure pressure difference is filled with mercury and water will fil the leads above the surface of mercury. The temperature of water remains constant throughout if the fow rate of water is 85 mm3 and throat diameter is 30mm and venture coefficient is C o. 98 What will be the manometer reading What wil be the power to operate the meter at full load If the pressure recovery is 90% of the differential pressure The density of water can be taken as 999 kg/m) Speciic gravity of mercury can be taken as 13.6 and water as 1 [6|
