A venturimeter is used to measure the flow of water in a 150 mm diameter pipe. The throat diameter of the venturimeter is 60 mm and the discharge coefficient is 0.9. If the pressure difference measured by a manometer is 10 em mercury, what is the average velocity in he pipe? Assume water has a density of 1000 kg/m3 nd mercury has a relative density of 13.6, 54

The turbine at C draws a power P kW. If the intake B has a diameter of de mm. The pressure dg(mm) dĄ(mm) at the intake B is Ps kPa and the velocity of the water (density = 1kg/L) at that point is v (m/s). The frictional losses between A and B are At neglected, and the exit A has a diameter of da B1 mm. Consider the data in the table to M = last two digits of your student ID P (kW) = 0.5M + 68.5 da(mm) = M + 150 dp (mm) %3D М + 400 PB (kPa) = M + 380 v (m/s) = 0.1M + 4 a- Calculate the velocity at the exit A b- Calculate the discharge at the exit A c- Calculate the turbine head d- Calculate the pressure at A m=13

Explain the measuring the pressure drop across a flow section or a flow device by a differential manometer.

A venturi meter having a throat diameter of 100mm is fitted into a pipeline which has a diameter of 250mm through which water is flowing. The pressure difference between the entry and throat tapping measured by a U-Tube Manometer containing mercury of a relative density of 13.6 and the connections are filled with the water flowing in the pipeline. If the difference of level indicated by the mercury in the U-tube is 0.63m, calculate: The theoretical volumetric flow rate and The actual volumetric flowrate if the coefficient of discharge is 0.9
