Calculate the pressure drop (in $10^5\mathrm{Pa}$.) due to the Bernoulli Effect as water goes from a 10-cm-diameter fire hose into a 2-cm-diameter nozzle, held horizontally, while maintaining a flow rate of $70\mathrm{L}/\mathrm{s}$. Assume that the density of water is 1000 $\mathrm{kg}/{\mathrm{m}}^3$ ? 19.5 13.5 17.5 21.5 15.5 11.5
