Characteristics of an IDEAL FLUID

An ideal fluid has the following properties

๐Ÿ‘‰It is incompressible, i.e., its density has a constant value throughout the fluid.

๐Ÿ‘‰Its flow is irrotational, i.e., the flow is steady or laminar. In an irrotational flow, the fluid does not rotate like in a whirlpool and the velocity of the moving fluid at a specific point does not change over time

๐Ÿ‘‰Many fluids change from laminar to turbulent flow as the speed of the fluid increases above some specific value. This can dramatically change the
properties of the fluid.

๐Ÿ‘‰Its flow is nonviscous or i.e., internal friction or viscosity is zero so that no energy is lost due the motion of the fluid.
