Question

Consider pure liquid water flowing at steady state through a long firehose with a contracting nozzle at the exit.  The hose and nozzle inlet diameter are the same and 1 inch larger than the nozzle outlet diameter.  Frictional effects in the hose are significant, causing the pressure to drop with length along the hose.  Pressure also drops in the nozzle due to contraction.  Assume the water is incompressible (as we normally treat liquids).  How would each of the following vary in the direction of flow?

Fillin the blanks using 

a.decarease

b.increase

c.stay the same

d.cannot tell
