9. Air is flowing through a pipe system with different diameters a. Rank the sections of the pipe from largest to smallest velocity. b. Rank the sections of the pipe from largest to smallest pressure. c. Rank the sections of the pipe from largest to smallest volume flow.
Expert Answer
The continuity equation is applied here , which states mass flow rate must be conserved . Solution :-(a) when the cross section of the pipe reduces , from the continuity equation , the velocity increases .The largest to smallest velocity of the section is Let , the velocity of Section A = Section B = Section C =
