The size of orifice is large
The velocity of flow is large
The available head of liquid is more than 5 times the height of orifice
The available head of liquid is less than 5 times the height of orifice
Higher surface tension
Lower surface tension
Surface tension is no criterion
High density and viscosity
Viscosity of a fluid is that property which determines the amount of its resistance to a shearing force
Viscosity is due primarily to interaction between fluid molecules
Viscosity of liquids decreases with increase in temperature
Viscosity of liquids is appreciably affected by change in pressure

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
