Chapter 8, Problem 150P
Air flows through a venturi meter with a 3-in.-diameter throat placed in a 6-in.-diameter line. Assume that the upstream pressure is 60 psi and the temperature is 68°F. Determine the maximum possible mass flow rate of air for which the assumption of incompressible flow is a valid engineering approximation. Compute the corresponding differential pressure reading on a mercury 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
a venturimeter with inlet and throat diameters 300 mm and 150 mm respectively is attached in a vertical pipe in which flow occurs from bottom to top. the distance between the point of entrance and to the point of throat of the venturimeter is 750 mm. if the difference of mercury levels in the two limbs of differential gauge is 220 mm, find the discharge passing through the vertical pipe. take co-efficient of discharge, Cd = 0.98.
A pitot tube is inserted into an air flow to measure the flow speed to measure flow speed. The Pitot tube is inserted into a 100mm diameter tube so that it points upstream into the flow and the pressure as show in figure 5 where p0 = stagnation point. The static pressure is measured at the same location in the flow, using a U-tube differential manometer. Consider density of air equal to 2.3kg/m3 and determine the air flow rate.
