W6.5 One flowmeter device, in wide use in the water supply and
gasoline distribution industries, is the nutating disk. Look
this up in the library, and explain in a brief report how it
works and the advantages and disadvantages of typical designs. Fundamentals of Engineering Exam Problems
FE6.1 In flow through a straight, smooth pipe, the diameter
Reynolds number for transition to turbulence is generally
taken to be
(a) 1500, (b) 2100, (c) 4000, (d) 250,000, (e) 500,000
FE6.2 For flow of water at 20°C through a straight, smooth pipe
at 0.06 m3/h, the pipe diameter for which transition to turbulence occurs is approximately
(a) 1.0 cm, (b) 1.5 cm, (c) 2.0 cm, (d) 2.5 cm, (e) 3.0 cm
FE6.3 For flow of oil [
0.1 kg/(m s), SG 0.9] through a
long, straight, smooth 5-cm-diameter pipe at 14 m3/h, the
pressure drop per meter is approximately
(a) 2200 Pa, (b) 2500 Pa, (c) 10,000 Pa, (d) 160 Pa,
(e) 2800 Pa
FE6.4 For flow of water at a Reynolds number of 1.03 E6 through
a 5-cm-diameter pipe of ro...
