Which one of the following statements about energy dissipation in fluids is correct?
(a) Streamline and turbulent flows lose energy at the same rate for the same mean speed.
(b) Streamline flow causes greater energy loss than turbulent flow of equal speed.
(c) For the same mean speed, turbulent flow causes more energy loss than streamline flow.
(d) For identical pipes and speeds, energy loss in turbulent flow is smaller because eddies store kinetic energy that can later be recovered.
