Unformatted text preview: Comment if this flow could be considered as compressible or incompressible? 5. Calculate the Reynolds number for the in the test section. Use a Moody Diagram to determine the friction factor. 6. Calculate the pressure drop across the ½” nominal diameter pipe. 7. Suppose the back pressure is varied to obtain a pressure at the back pressure gauge of 30 psig for the same rotameter conditions (60psig, 12scfm). What is the pressure drop in the ½” nominal diameter pipe? Explain any difference. Does this differ from liquid flow?...
