Quiz 8 Q. 1 This is the region of 2,300<Re<10,000 Q. 2 If the flow is turbulent and the pipe is rough the Moody chart (Fig A-27, pg. 1029) shows that there are regions where the value of ‘f’ does not depend on Re (the value is onstant). Q.3 All these are ways to get a numer for the friction factor. Q.4 Mechanical energy is converted to heat (and lost) resulting in head loss, entropy is generated by friction making the heat. Q. 5 See page 553. Q. 6 see page 557, for example Q. 7 & 8 Lift is perpendicular, drag is parallel. Q. 9 see fig 15-19 on page 592 Q. 10 Cylinders have a lot of drag due to flow separation see Fig 15-33. Question 1 There is a range in Reynolds number where it is possible to have either laminar or turbulent flow depending on the details of the flow situation X True 100% False 0% Question 2 Friction factor depends on Reynolds numbers under all circumstances True 4.762% X False 95.238% Question 3 The Moody chart, the Colebrook equation, and Haaland expression all are
