Air, at 68 degrees. F. has a mass flow rate of 0.96lbm/5 as it flows through a 1.24 to diameter pipe. What is its Reynolds number? Question 3 10 Points Water at 66 degrees f is thowing at a steady velocity of 35 ft/s in a 3 inch schedule 40 pipe. (5ee appendix A. 2 in De Nevers.3rd ecition.) What is its Reynoldis number? Add yous anawer: Question 4 Water Hows in pipe. inidally at 20 degrecs C. Ihe flow is at ready stote and the pipe s diamieter is constant, As the liquid. travels through the pibe hest is exchanged with the surroundings and as a result the liquid increases fo ternnerature. What can be sald obout the change in the feynolds number as the liquid flaws throygh this ploe and is heared? The Reynotds number will incerate. the Reynolds number will decreace. Ihe Reynolds namiter wil stay the cane. Hot encugh intortation is aven to know how Reyaolds number nietic changet
