An equation for the frictional pressure loss (Delta p) (inches (mathrm{H}_{2} mathrm{O}) ) in a circular duct

Question:

An equation for the frictional pressure loss $\Delta p$ (inches $\mathrm{H}_{2} \mathrm{O}$ ) in a circular duct of inside diameter $d$ (in.) and length $L$ (ft) for air flowing with velocity $V(\mathrm{ft} / \mathrm{min})$ is

\[ \Delta p=0.027\left(\frac{L}{d^{1.22}}\right)\left(\frac{V}{V_{0}}\right)^{1.82} \]

where $V_{0}$ is a reference velocity equal to $1000 \mathrm{ft} / \mathrm{min}$. Find the units of the "constant" 0.027.
