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 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 nominal diameter pipe? Explain any difference. Does this differ from liquid flow?...
