slope | Weight coefficient (1 - 10) | Reason given coefficient |
0.000247 - 7.959794 | 4 | For supply pressure into the transition pipeline need to cost + because of low or zero slope and water low speed and could flow fluently possible to sediment into the pipe + sedimentation path and water low speed (drop water speed cause of friction) + necessity for pumping water + cost of constructing pumpage station (external cost of electricity supply and so on) |
7.959794 - 15.919342 | 3 | For supply pressure into the transition pipeline need to cost + erosion of pipe |
15.919342 - 23.878889 | 4 | For supply pressure into the transition pipeline need to cost + increase friction coefficient of pipe |
