For the velocity function,
the equation of the streamline passing through (1,1) is
A steady, incompressible, 2-D velocity field is given by
u = x + y + 2
v = x - y - 3
The coordinate of stagnation point (if it exists) is
The velocity along the centreline of a nozzle of length L is given by
V - velocity in m/s,
t = time in seconds from commencement of flow,
x = distance from inlet to the nozzle
The total acceleration when t = 3s, x = 0.5 m and L - 1 m is
A pathline represents
There is no geometrical distinction between the streamline, pathline and streakline in case of
Which of the following statement is wrong?
Streamline spacing varies inversely as the velocity; converging of streamline in any particular direction shows accelerated flow in that direction.
When fluid flows in a curved path and requires no external impressed constant force, the fluid motion is known as
Match List-I (Example of flow) with List-Il (Type of flow) the following:
When a cylindrical vessel containing a liquid is revolved at constant angular velocity about its vertical axis, the pressure
An open cylindrical tank is 15 cm (radius) x 150 cm (height) and is filled with water to a depth of 80 cm. What is the maximum angular velocity with which it can be rotated so that center of the bottom of the tank is just exposed?
When the point at the center of the base is just exposed, the depth of fluid at center becomes zero. Therefore, the depth of parabola equals the height of tank, y = 150 cm
