Question

Which is not the assumption made in writing the linear momentum equation in x-direction as,?

Answer 1

This principle is directly obtained from the linear momentum equation by taking the cross -product of both the force and the linear ...

Answer 2

Answer:

The equations are derived from the basic principles of continuity of mass, momentum, and energy. Sometimes it is necessary to consider a finite arbitrary volume, called a control volume, over which these principles can be applied. This finite volume is denoted by {\displaystyle \Omega } \Omega and its bounding surface {\displaystyle \partial \Omega } \partial \Omega . The control volume can remain fixed in space or can move with the fluid.
