Pressure loss along a pipe pumping water is 6.6Pa. If the pipe is 2.1m long, what angle (in degrees) must it be orientated to the horizontal to overcome the pressure drop?
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 me-ter 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.
