The pressure drop for a fluid with a viscosity of $5 \mathrm{cP}$ and a density of $0.8 \mathrm{~g} / \mathrm{cm}^{3}$ flowing at a rate of $30 \mathrm{~g} / \mathrm{s}$ in a $50 \mathrm{ft}$ long $1 / 4 \mathrm{in}$. diameter pipe is $10 \mathrm{psi}$. Use this information to determine the pressure drop for water at $60^{\circ} \mathrm{F}$ flowing at $0.5 \mathrm{gpm}$ in a $2 \mathrm{in}$. diameter pipe. What is the value of the Reynolds number for each of these cases?
