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

the liquid particles at all sectons have the same velocities

the liquid particles at different sections have different velocities

the quantity of liquid flowing per second is constant

each liquid particle has a definite path
