A Venturi meter is a device used to measure the flow in a pipe or tube. The meter consists of a tapered reduction of the pipe diameter, followed by an expansion back to the original diameter (see figure below). Pressure taps are used to measure the pressure upstream of the meter and at the narrowest point of the meter, and the flow rate can be determined from the pressure difference between the two points. Flow PhTap For this problem, consider a Venturi meter with a 1.2-inch throat has been installed in a 3-inch diameter pipe transporting water. Use a spreadsheet to predict the performance of the meter by calculating the pressure difference (OP = P. -P) in units of psi, for a series of flow rates ranging from 0 to 100 gal/min (GPM) in increments of 5 GPM. Make sure that all variables (pipe and throat diameters, fluid density) are displayed in separate cells. You may neglect friction. - Plot a calibration curve for the flow meter (flow rate on the y-axis, pressure difference on the x-axis). - The pressure indicator on the Venturi meter shows a pressure difference of 2.75 psic; use the calibration curve to estimate the flow of water
