Fluid Statics Study of fluid at rest, i.e. not in motion or not flowing On any plane, shear force is zero(no velocity gradient or shear deformation) hence only pressure forces exist

Flow Classification Ideal Fluid Flow Frictionless(zero viscosity) Incompressible Can be solved mathematically Real Fluid Flow
