Questions 1 Referring To Figure 7 2 Recall That Bernoulli S Equation Was Applied To Points 1 And 2 Where The Pressure 2 (24.26 KiB) Viewed 11 times
Questions 1. Referring to Figure 7.2, recall that Bernoulli's equation was applied to points 1 and 2 where the pressure difference measurement is made. The theoretical equation, however, refers to the throat area for point 2 (the orifice hole diameter) which is not where the pressure measurement was made. Explain this discrepancy and how it is accounted for in the equation formulation. 2. Which meter in your opinion is the best one to use? 3. Which meter incurs the smallest pressure loss? Is this necessarily the one that should always be used? 4. Which is the most accurate meter? 5. What is the difference between precision and accuracy?
actual flow rate (measured in the laboratory). The ratio of actual to theoretical flow rate leads to the definition of a discharge coefficient: C, for the orifice meter and C, for the nozzle. Ah 2 FIGURE 7.2. Cross sectional view of the orifice meter. ΔΗ 2 FICU
