14.7 Viscosity and Turbulence | University Physics Volume 1

A fire hose has an inside diameter of 6.40 cm. Suppose such a hose carries a flow of 40.0 L/s starting at a gauge pressure of [latex] 1.62\,×\,{10}^{6}\,{\text{N/m}}^{2} [/latex]. The hose goes 10.0 m up a ladder to a nozzle having an inside diameter of 3.00 cm. Calculate the Reynolds nuers for flow in the fire hose and nozzle to show that the flow in each must be turbulent.
