A long horizontal hose of diameter 3.8 cm is connected to a faucet. At the other end, there is a nozzle of diameter 1.8 cm. Water squirts from the nozzle at velocity 38 m/sec. Assume that the water has no viscosity or other form of energy dissipation.

a) What is the velocity of the water in the hose ?

this is no prob

A1V1 = A2V2

8.61m/s OK

b) What is the pressure differential between the water in the hose and water in the nozzle ?

i am stuck on this one.

2. Relevant equations

3. The attempt at a solution

heres what im doing...

use bernoulli..

P2-P1 = (1/2pv^2)1 - (1/2pv^2)2

P2 - P1 = 634.934Pa

this is wrong.

please help ! thanks
