    The fluid which has zero viscosity is called as an ideal fluid. There is not existence of shear force because of zero viscosity. Surface tension in any fluid depends upon its viscosity. As viscosity in ideal fluid is zero, there will be no surface tension in an ideal fluid. The compressibility of an ideal fluid should be zero, thus ideal fluid is the fluid which is incompressible. The ideal fluid does not exist. It is a hypothetical fluid.
