Chapter 9, Problem 1CP

Explain the fundamental differences between a flow domain and a control volume.

To determine

The difference between a flow domain and a control volume.

Explanation of Solution

The difference between Control Volume and the Flow domain is tabulated below:

S.No.	Control volume	Flow domain
$1$	The control volume analysis of an object is the integral analysis.	The flow domain analysis of an object is the differential analysis.
$2$	The only overall features of the flow are calculated in the control volume analysis.	The flow properties like velocity or pressure can be calculated at all points inside or outside of the object.
$3$	The information of flow like velocity or pressure at the points inside the object cannot be obtained in this analysis. So the interior of the object is treated as a black box.	The flow domain is the differential analysis as an analysis of the millions of tiny control volumes throughout the flow field.
