Stream function cannot be defined for
Question 3
Which of the following velocity field presents a possible fluid flow?
i. u = y + x , v = x – y
ii. u = y – x , v = x + y
iii. u = x – y , v = x – y
Question 4
The velocity potential for a two-dimensional flow is given by
The flow rate between the streamlines passing through points (1, 2) and (2, 3) is
The flow rate between the streamlines passing through points (1, 2) and (2, 3) is Question 5
The discharge was measured in a small stream. It was found that the depth of flow increased at a rate of 0.20 m/hr. If the discharge at that section was 30 m3/s and the surface width of the stream was 18 m, then the discharge at a section 1200 m upstream was ________m3/s.
