Question

9.
Flow net is drawn for a two-dimensional
boundary. The velocity of uniform flow at
approach is 1.2 m/s. The size of the square
is 1.2 cm side. The size of the square at
another location in the stream tube is 0.5
cm. The velocity at this point is
a) 1.44 m/s
b) 2.4 m/s
c) 2.88 m/s
d) 3.4 m/s

Answer 1

Answer:

On a flow net diagram, the distance between two consecutive steam lines at two successive sections are 1 cm and 0.5 cm respectively. If the velocity at the first section is 1 m/sec, the velocity at the second is

[A].1.0 m/sec[B].0.5 m/sec[C].2.0 m/sec[D].2.5 m/sec[E].3 m/sec.

Answer: Option C

Answer 2

Answer:

c)2.88

Explanation:

1.2 cm X 1.2 m/s = 0.5 cm X V2

V2 = 1.44/0.5

V2= 2.88 m/s
