Q3.For a 2-D flow field, the stream function ψ is given as ψ = 3/2(y2 - x2). The magnitude of discharge occurring between the stream line passing through
points (0, 3) and (3, 4) is
Q4.The ratio Nf / Nd is known as shape-factor where Nf is the number of flow
channels and Nd is the equipotential drop. The flownet always drawn with a
constant b/ a ratio where b and a are distance between two consecutive flow lines
and equipotential lines respectively. Assuming that b/a ratio remains same, the
shape factor of a flow net will change if the
