Be horizontal
Make an angle in direction of inclination of inclined plane
Make an angle in opposite direction to inclination of inclined plane
Any one of above is possible
Velocity of liquid
Pressure of liquid
Area of mouthpiece
Length of mouthpiece
The direction and magnitude of the velocity at all points are identical
The velocity of successive fluid particles, at any point, is the same at successive periods of time
Velocity, depth, pressure, etc. change from point to point in the fluid flow.
The fluid particles move in plane or parallel planes and the streamline patterns are identical in each plane

Any weight, floating or immersed in a liquid, is acted upon by a buoyant force
Buoyant force is equal to the weight of the liquid displaced
The point through which buoyant force acts, is called the center of buoyancy
Center of buoyancy is located above the center of gravity of the displaced liquid

When its meatcentric height is zero
When the metacentre is above C.G.
When its e.g. is below its center of buoyancy
Metacentre has nothing to do with position of e.g. for determining stability
The pressure at any location reaches an absolute pressure equal to the saturated vapour pressure of the liquid
Pressure becomes more than critical pressure
