GATE Civil Engineering (CE) 2013 Solved Paper

The ratio N_f/N_d is known as the shape factor, where N_f is the number of flow lines and N_d is the number of equipotential drops. Flow net is always drawn with a constant b/a ratio, where 'b' and 'a' are distances between two consecutive flow lines and equipotential lines, respectively. Assuming that b/a ratio remains the same, the shape factor of a flow net will change if the
