DISPLAY
A vertical pipe is partially or completely closed at the upper
end. The pipe initially contains air at atmospheric pressure in
its upper half; and the lower half is filled by water.
At the bottom of the pipe there is free communication with a
large reservoir of water into which the pipe has been pushed so
that its upper end is flush with the surface of the reservoir.
Both air and water are initially at rest; but the excess pressure
causes the water level at first to rise in the tube, whereafter
an oscillation ensues.
The time considered is 5 seconds, divided into 100 equal
intervals. The tube is 20.0m long, divided into 20 equal
intervals.
The water is incompressible and has a density of 1000.0
kg/m3. The air is compressible,obeying the law
rho=(pressure/1.E5)**(1.0/1.4)
PHOTON USE commands are provided for graphical display.
