$(8-30$C$)$ The head loss for a certain circular pipe is given by h$,=0\mathrm{.}0826/$L$/$D$),$ where f is the

friction factor $($dimensionless$),$ L is the pipe length, Vis the volumetric flow rate, and D is the pipe diameter.

Determine if the $0\mathrm{.}0826$ is a dimensional or dimensionless constant. Is this equation dimensionally homogeneous as it stands?
