$*7-56.$ Two sources, each having a strength of $\backslash (3\backslash$mathrm$\{$~m$\}^\{2\}/\backslash$mathrm$\{$s$\}\backslash ),$ are located as shown. Determine the $\backslash ($ x $\backslash )$ and $\backslash ($ y $\backslash )$ components of the velocity of a fluid particle that passes point $(\backslash (3\backslash$mathrm$\{$~m$\},4\backslash$mathrm$\{$~m$\}\backslash )).$ What is the equation of the streamline that passes through this point?

Prob. $7-56$
