A streamline is a line that is tangential to the instantaneous velocity direction (velocity is a vector, and it has a magnitude and a direction). To visualize this in a flow, we could imagine the ...

When a relationship between two variables is defined by a curve it means that the gradient, or rate of change is always varying. An average speed for a journey can be found from a distance-time ...

The need to measure the frequency on each pulse motivated the development of the IFM receiver. The IFM is basically a crystal video receiver with the addition of a frequency sensing method. The usual ...
