Water flow around a concrete bridge pier that has a cross section in the shape of a Rankine oval, formed by superimposing a line source and line sink placed $a=1m$ apart, and each having a strength of $q=8\frac{m^2}{s},$ as shown below. If uniform flow around the body is $U=10\frac{m}{s},$ calculate the required dimension b for the pier.

$b=(\frac{q}{U}a+a^2)\frac{1}{2}$

$b=$

A $m$
