A venturi meter is introduced in a 300 mm diameter horizontal pipeline carrying a liquid under a pressure of 150 kPa. The throat diameter of the meter is 100 mm and the pressure at the throat is 400 mm of mercury below atmosphere. If 3% of the differential pressure is lost between inlet and the throat, determine the flow rate of the pipeline.
COMPLETE SOLUTION
1. A venturi meter is introduced in a 300 mm diameter horizontal pipeline carrying a liquid under a pressure of 150 kPa. The throat diameter of the meter is 100 mm and the pressure at the throat is 400 mm of mercury below atmosphere. If 3% of the differential pressure is lost between inlet and the throat, determine the flow rate of the pipeline. 4. An rectangular orifice with height 0.4 m and width of 0.6 m was used to measure the flow of a certain channel. Flow was controlled such that the entirely of the discharge will be focused and exit on the orifice. Upon stabilization of conditions, it was observed that the height of the water above the orifice can be taken as 1.2 meters and for a certain section upstream before the orifice, velocity can be considered constant at 1.7 meters per second. Assume your own water temperature and compute for the stream discharge considering a discharge velocity of 0.6812.
