How the Von-Karman momentum integral equation expressed is (\[\theta \] is momentum thickness)? 

A) \[\frac{{{\tau }_{0}}}{\frac{1}{2}\,\rho \,U_{\infty }^{2}}=\frac{\partial \theta }{\partial x}\]      

B)   \[\frac{{{\tau }_{0}}}{2\,\rho \,U_{\infty }^{2}}=\frac{\partial \theta }{\partial x}\]

C) \[\frac{{{\tau }_{0}}}{\rho \,U_{\infty }^{2}}=\frac{\partial \theta }{\partial x}\]            

D) \[\frac{{{\tau }_{0}}}{\frac{1}{3}\,\rho \,U_{\infty }^{2}}=\frac{\partial \theta }{\partial x}\]
