This demonstrates laminar flow of a viscous fluid between two plates. The plot shows fluid velocity as a function of vertical distance. Velocity is proportional to the length of the arrows. The lower plate is stationary and the upper plate is either stationary or moves to the right; its velocity is set using the slider. The pressure gradient is also set with a slider.
