Macmillan Learning What is the Reynolds number $Re$ for for a fluid traveling through a pipe with a diameter of 0.51 m, and the the fluid has a dynamic viscosity of $2.7 \times 10^{-1}$ Pa-s, a density of 510 kg/m$^3$, and travels at a mean fluid velocity of 10.7 m/s? $Re =$ 10000 The fluid through the pipe in the given scenario is turbulent. laminar.

The Reynolds number is a dimensionless group defined for a fluid flowing in a pipe as $R e=D u \rho / \mu$ where $D$ is pipe diameter, $u$ is fluid velocity, $\rho$ is fluid density, and $\mu$ is fluid viscosity. When the value of the Reynolds number is less than about $2100,$ the flow is laminar- -that is, the fluid flows in smooth streamlines. For Reynolds numbers above $2100,$ the flow is turbulent, characterized by a great deal of agitation. Liquid methyl ethyl ketone (MEK) flows through a pipe with an inner diameter of 2.067 inches at an average velocity of $0.48 \mathrm{ft} / \mathrm{s}$. At the fluid temperature of $20^{\circ} \mathrm{C}$ the density of liquid $\mathrm{MEK}$ is $0.805 \mathrm{g} / \mathrm{cm}^{3}$ and the viscosity is 0.43 centipoise $\left[1 \mathrm{cP}=1.00 \times 10^{-3} \mathrm{kg} /(\mathrm{m} \cdot \mathrm{s})\right]$. Without using a calculator, determine whether the flow is laminar or turbulent. Show your calculations.
