Now i get \epsilon_b = - \frac{8...

Now i get

\epsilon_b = - \frac{8 \mu_t}{D^2} \int^{D/2}_{0} r (\frac{\partial \bar{u_x}}{\partial r})^2 dr

and does anyone know how to compute this integration?

how to calculate the viscous dissipation rate for a turbulent pipe flow

The transport equation for the mean kinetic energy reads as follows:

0 = -\frac{\bar{u_x}}{\rho} \frac{\partial \bar{p}}{\partial x} - \frac{1}{r} \frac{\partial}{\partial r}(r...
