Probem$1$: A liquid at $293$ K flow at a the rate of $0\mathrm{.}7k\frac{g}{s}$ in a glass pipe having a diameter of $64$ mm $.$ The liquid density is $1000k\frac{g}{m^3}$ with a viscosity of $2$ cp $.$

$($a$)$ Calculate the Reynolds number. Is this flow turbulent or laminar?

$($b$)$ Calculate the flow rate needed in $\frac{m^3}{s}$ and velocity in $\frac{m}{s}$ for a typical flow rate that is laminar. $($Hint: Choose a Reynolds number within the laminar region.$)$
