5. The ratio Nf/Nd is known as shape factor, where Nf is the number of flow lines and Nd is the number of equi-potential drops. Flow net is always drawn with a constant b/a ratio, where b and a are distances between two consecutive flow lines and equi-potential lines, respectively. Assuming that b/a ratio remains the same, the shape factor of a flow net will change if the
