a A horizontal US schedule 40 pipe has the Nominal Diameter of 5 inches. Gasoline fuel is flowing inside the pipe with a volumetric flowrate of 124.6 gallons/min. A Venturi meter is fixed in the pipe with the constriction (throat) diameter equal to half the internal diameter of the main pipe. A manometer partially filled with water is connected to the pipe and the Venturi meter. Answer the following questions. (5 pts) 1. Calculate the average velocity and Reynolds number of the gasoline flow in the pipe. (5 pts) 2. Draw the process diagram with all information and parameters given. 3. Calculate the pressure drop in the Venturi meter in terms of the height of the water column in the (15 pts) manometer (in mm H2O). 4. If the friction loss has to be considered in this process, what is the difference in the water levels of (3 pts) the manometer? (The discharge coefficient, Cv, is given in the Appendix) (2 pts) 5. Comment very briefly on the energy efficiency of this Venturi meter
