Explain the operating principles of a venturi flowmeter. Derive the flow equation.
Question - You must discuss in detail the way in which the pitot tube and nozzle flow meter are used to calculate velocity or volume flow rate. Write the velocity (or flow rate) equations for both and a detailed description of the what you did.
4. If the pressure difference between points 1 and 2 below is 90 psi, what will be the flow
rate? The pipes are galvanized iron with ks = 0.0005 ft. Take kinematic viscosity equal to
1.06 x 10-5 ft²/s and neglect minor losses.

The differential manometer fluid has a specific gravity of 1.10. The calibration is accomplished by connecting the orifice meter in series with a rotameter that has previously been calibrated for acetone, adjusting a valve to set the flow rate, and recording the flow rate (determined from the rotameter reading and the rotameter calibration curve) and the differential manometer reading, h. The procedure is repeated for several valve settings to generate an orifice meter calibration curve of flow rate versus h. The following data are taken.
