| Abstract: | Bernoulli equation plays an important role in hydraulics and describes the conversion rule of kinetic energy,gravitational potential energy and pressure potential energy in the steady flow.Bernoulli equation experiment can clearly show the conversion phenomenon by total head line and piezometer head line.The computer program could intuitively show the main phenomenon of experiment,which consists of a visual window interface,command buttons and menus,as the main control units.Computer simulation based on the real steps of the experi-ment,draws the experimental equipment,shows the flow process and deals with the data,plots the head line graphics for analysis.The computer program does not only gives students a roughly knowledge about experiment before doing it,but also helps teachers doing their work. |
