$(6$ marks$)$ Compute the Reynolds number for the blood in the capillaries under these

conditions, and state whether the blood flow is turbulent in the capillary. Assume a single

capillary has a dynamic viscosity of $0\mathrm{.}04$ poise, and blood density of $1\mathrm{.}05$ g$/$cm$3$

$.$ What

would the blood velocity have to be to promote turbulent flow? Given the result, how

likely is it for the blood in the capillary to become turbulent and why?

Use a cut$-$off of $4000$ for the turbulent flow for the Reynolds number.
