A nozzle is attached to the end of a fire hose with an inside diameter D = 75mm. The nozzle has a smooth profile and an outlet diameter of 25 mm. This flow can be treated as incompressible, steady, lossless and along a streamline. The design pressure at the nozzle inlet is p1 = 640 kPa (gauge). Determine the maximum volumetric flow rate this nozzle can deliver.

a) 17.7 m/s

b) 17.7 L/s

c) 17700 L/s

d) 17700 m/s
