b) The positive and negative characteristics equation of water hammer are: C+: pcdv + dP - pg sin 0 dx + pfulul 2D C-: pcdv - dP + pg sin 0 dx pfv|v| 2D 1 dx = 0 - dx = 0 (Eq. 1.1) (Eq. 1.2) (i) Draw an x-t grid system that illustrates the computation process of the water hammer system. Show the corresponding positive and negative characteristics (C+ and C-), and nominate the points of interest as points A, B and P. (ii) According to your x-t grid system, transform the dv and dp terms of Equations 1.1 and 1.2 into different forms, i.e. dv=vp-VA, etc. (7 marks)
