We have derived the Continuity Equation, 4.10 using Cartesian Coordinates. It is possible to use the same system for all flows. But sometimes the equations may become cumbersome. So depending upon the flow geometry it is better to choose an appropriate .....

Thanks a lot for the derivation, I was having some issues picturing the spherical element. A better way of doing it is by doing the grouping done in the last line using the product rule when you calculate each difference in mass flow rate. Also if you lea...

In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a fixed point and an angle from a fixed direction. The fixed point (analogous to the origin of a Cartesian s...
