4.16 Water flows steadily through a fire hose and nozzle. The hose is 75-mm-ID, and the nozzle tip is 35-mm-ID; water gage pressure in the hose is 510 kPa, and the stream leaving the nozzle is uniform. The exit speed and pressure are 32 m s and atmospheric, respectively.

Find the force transmitted by the coupling between the nozzle and hose. Indicate whether the coupling is in tension or compression.
