Once you know the velocity of the fluid, you can calculate flow using the cross sectional area of the pipe. In this video, I walk through some of the details that electrical engineers have worked ...

In a constant density flow, therefore, the cross-sectional area of the streamtube gives information on the local velocity. As an example, consider steady, constant density flow over a cylinder, where ...

Calculate resistance and cross section area, A, in mm 2 (A = \(\frac {{\pi ... This makes it more difficult for the current to flow, and causes resistance. The resistance of a long wire is ...

The inlet and outlet cross-sectional areas of a valve are much larger than the control area, such as the cage or the area around the plug and seat. Because the total flow at any location in the valve ...

LEVITT 1 directly compares a resistance for flow of liquid water with one ... an equivalent air path ; this is a tube of air of unit cross-sectional area of such a length that, with the equivalent ...
