Properties of Ideal Fluid are :
- Steady flow...... it is all moving at the same speed. What goes into a tube comes out of a tube. It doesn't speed up in one place and slow down in another.
- In-compressible flow..... liquids are hard to compress, they behave almost like solids. the molecules are very close together so they repel each other if you try to compress them
- Again there are no velocity gradients or changes in velocity due to the drag of the liquid molecules on each other, they all move at the same speed.
- They do not form vertices and move in circles, they move linearly, respond to the push of the molecules behind them.

An Ideal fluid has
the following properties.
- It is incompressible i.e., its density is constant.
- Its flow is irrotational i.e., its flow is smooth with no turbulence in the flow.
- It is non-viscous i.e., there is no internal friction in the flow and hence the fluid has no viscosity.
- it's flow is steady i.e., it's velocity at each point is constant in time.
