Unformatted text preview: Westfield College] Q3.9 Solution The conditions that must be fulfilled in drawing the flownet are equipotentials and flowlines cross at 90 elements in the flownet have the same breadth as length, forming curvilinear squares impermeable boundaries and the centreline are flowlines u = 0 on the top flowline, i.e. the x m equipotential intersects the top flowline at x m above the datum for the measurement of head (phreatic surface condition for an unconfined flownet) The flownet is sketched on Figure Q3.9. The phreatic surface condition is satisfied by trial and error, along with the rest of the conditions above. Note: capillary rise effects are neglected. Figure Q3.9...
