Fluid flow kinetic energy evaluation

Evaluate the kinetic energy correction factor a in Bernoulli s equation for turbulent flow assuming that the 1/7 power law velocity profile [Eq. (6-36)] is valid. Repeat this for laminar flow of a Newtonian fluid in a tube, for which the velocity profile is parabolic. 

In order to obtain the kinetic energy correction factor, a, for insertion in the mechanical energy balance, it is necessary to evaluate the average kinetic energy per xmit mass in terms of the average velocity of flow. The calculation procedme is exactly similar to that used for Newtonian fluids, (e g. see [Coulson and Richardson, 1999]). 

Exergy flows are identical to power in the case of the change of potential, kinetic, or electric energies. To evaluate the flow i of a fluid mixture, specific exergies e, in kj/kg for every mass flow w, in kg/s must be calculated.
