-
Discharge from a 24 inch pipe of water at 10 ft/sec will be __________ ft3/sec.
-
Paper pulp is an example of __________ fluid.
|
A.
It is always parallel to the main direction of the fluid flow.
|
|
B.
It is a line across which there is no flow and it is equivalent to a rigid boundary.
|
|
C.
Streamlines intersect at isolated point of zero velocity and infintie velocity.
|
|
D.
The fluid lying between any two streamlines can be considered to be in isolation and the streamline spacing varies inversely as the velocity.
