@Rouben Rostamian  u= crf, v=crg, w=(c*nue*h)^1/2 are the similarity transformations

@Kitonum Thanks dear, can you please draw stream lines in 3 dimension for this problem, actually i want to draw these lines

@Kitonum dear, actually i am interested in plotting stream tubes

@Kitonum sorry, the exact form of eq1 is

eq1=diff(h(eta),eta)+2f(eta);
