Unformatted text preview: results by TranSAM. (d) Plot pressure head history at the valve (meaning the upstream side), Of course, you should use the output of TranSAM. Indicate the period of water-hammer. (e) Plot pressure head history at the mid-length of the pipe; indicate the period of water-hammer. (f) Change wavespeed of water-hammer, plot pressure head history at the valve. Discuss the effect of wavespeed. (g) Change friction factor, plot the pressure head history at the valve. Discuss the effect of friction factor. (h) Add vapour cavitation in the model; explain the irregular pattern in the pressure history. Comment on Joukowsky relation for design of pipeline. (hint: change VAPCAV to 1, which turn on the vapour cavitation in the model, and the lowest pressure can not be lower than vapour pressure.)...
