Question

3. [1pt]
Consider the following statements about fluid flow.
(Select T-True, F-False, G-Greater than, L-Less than, E-Equal to. If the first is T the second F and the rest G, enter
TFGGGG).

A) As fluid flows through a pipe the pressure at a narrow point is ... the pressure where the pipe is wider.
B) Bernoulli's equation applies to viscous fluids.
C) Streamlines often cross each other.
D) Bernoulli's equation is a statement of conservation of energy.
E) Bernoulli's equation assumes that the fluid is incompressible.
F) If the radius of a water pipe becomes twice as large the flow speed of a non viscous fluid will be .... one fourth of its initial value.

Explanation / Answer

A) Less than

By using bernoulli's theorem

Pn + (0.5) p Vn2 = Pw + (0.5) p Vw2

Vn> Vw

Hence Pn < Pw

B)False

C)False

D)True

E)True

F)Equal to
