This equation is called the continuity equation for steady ... A streamline is a line that is tangential to the instantaneous velocity direction (velocity is a vector, and it has a magnitude and a ...

Although these restrictions sound severe, the Bernoulli equation is very useful, partly because it is very simple to use and partly because it can give great insight into the balance between pressure, ...

The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time. \(\text{Gradient} = \frac{{change\,in\,velocity ...

The only difference between velocity and speed is that velocity has a direction, and so is a vector quantity. Average velocity = \(\frac{\text{displacement}}{\text{time}}\) Displacement is the ...

Bernoulli's equation is a simple but incredibly important equation in physics and engineering that can help us understand a ...
