sheet: Venturi Meter for Measuring Flow Rates - CHESS 3. When deriving the equation above, what was ignored that makes C, necessary; do some reading on this; it is not just because you ignore frictional losses, though that is part of it. Why is the C, correction factor so close to 1.0? 4. Calculate the volumetric flow rate for each valve setting in Table 1 using the data you collected for outlet volume and time to get the measured value, and the pressure drop between points 1 and 3 and equation in question 2 to get the calculated value. Use the literature value for the venturi coefficient (C) of 0.98. V calculated Valve setting Vmeasured=V/t [mL/s] AP = pg(hi-h) [Pa] [mL/s] Fully Open Partially Closed position (1) Partially Closed position (2) Compare the measured flow rates to the calculated values and discuss possible reasons for differences between Vmeasured and Vcalculated- 5. Calculate the venturi coefficient from your data and compare it to the literature value of 0.98. Use the equation derived in question 2 above. Using the measured flow rate, pressure drop data, and diameter values, obtain Cv using the slope from a linearized plot. Attach your plot to this assignment. Cy = 2. Worksheet: Venturi Meter for Measuring sheet Due: Homework Problems WE 1. What are the advantages and disadvantages of tesinga Kenturi meter compared to an orifice , Hint: You will need to do some reading in your textbook and/or review on-line information 3 2. Derive the rearranged energy balance below for the venturi meter. Show your work. Hints: 1) Ignore frictional losses in the energy balance between points 1 and 3 in the venturi. 2) Use the continuity equation to describe point 1 velocity in terms of throat velocity 3. 7D; 3) Substitute ) = 0 4) Rearrange for V and multiply your result by Cy, the venturi coefficient. 4 V = (ID}/4).
