Good analogue for a lumped constant delay line...
An ordinary tube suffices for the distributed model. The
hydrodynamic model is an exact analogue of the electrical
system.
For example. Charge a tranmssion line to some DC potential.
Now put a matched resistor across one end. The line discharges,
and the current pulse is twice the electrical length of the line. Why?
Plug one end of a tube, and fill with water. Put your thumb
over the open end, and tilt so the tube is horizontal.
Remove thumb.
Will the water all come out at once? Or what? Do it and
see for yourself. Look closely at the tube, but
don't spill water on your shirt 'cause you're so
fixated on the tube.
