Extracted text: Water flows through a 28 cm (length) rotameter (Type A) with an internal diameter of 25 mm at the top and 20 mm at the bottom. The float has a diameter of 20 mm, a volume of 6.1 cm and a specific gravity of 5.3. 15. Assuming that Az/A, is negligible, what is the area (in mm² to 5 significant figures) of the annulus when there is a flow of 380 I/hr water? Assume Co = 0.97 16. Using the same constant Cp value, recalculate the area of the annulus assuming Az/A, is not negligible (in mm? to at least 5 significant figures). 17. What is the final value of the linear flowrate through the annulus? (m/s) 18. What is the final Reynolds number through the annulus? 19. How far from the bottom is the float under these conditions? (cm) Answer the following questions as true or false: 20. A rotameter is typically placed vertically while an orifice meter is placed horizontally 21. An orifice meter requires only a change in pressure of the pipe to calculate the flowrate 22. An orifice meter is an example of a variable area flow meter 2PfluidVfloat(Ploat-Pfluid)E CDA2 Given: G = ṁ = Anoat(1-()
