Homework Help: Physics help 2 please **

A garden hose is attached to a water faucet on one end and a spray nozzle on the other end. The water faucet is turned on, but the nozzle is turned off so that no water flows through the hose. The hose lies horizontally on the ground, and a stream of water sprays vertically out of a small leak to a height of 0.85 m. What is the pressure inside the hose?
? kPa

Use the variable-height Bernoulli equation again.

The velocity of water inside the hose and at the top of the stream is nearly zero, so the change in (density)*g*y equals the change in P

P -Po = (density)* g * 0.85 m
Po is atmospheric pressure
