engineering recuitment AAI JE Technical Mock Test 2020-21 Fluid Mechanics Fluid Kinematics Continuity Equation
The continuity equation is given below.
\(\frac{{\partial u}}{{\partial x}} + \frac{{\partial v}}{{\partial y}} + \frac{{\partial w}}{{\partial z}} = 0\)
1
is valid for steady flow whether the flow is compressible or incompressible
2
is not valid for incompressible, unsteady flow
3
is valid for incompressible flow whether the flow is steady or unsteady
4
is valid for ideal fluid flow only
