Blood $($density $=1060$ kg$/$m$^3,$ viscosity $=0\mathrm{.}0012$ Pa s$)$ flows through a blood vessel whose diameter

is $2\mathrm{.}45$x$10-4$ m and whose length is $0\mathrm{.}18$ meters. The pressure drop from one end of the blood vessel

to the other is $180.$ Pa$.($a$)$ Calculate the blood flow $($in m$^3/$s$)$ in the blood vessel. $($Assume viscous

laminar flow.$)($b$)$ Determine the Reynold$$s number for the flow. $($c$)$ For fluid flowing through a

cylindrical tube, the flow will be laminar if the Reynold$$s number is below $2300.$ Was the

assumption of laminar flow appropriate?
