Question

I'm given a problem: "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 the small leak to a height of 0.76 m. Find the gauge pressure of the water:

Inside the hose: I used P=(rho)gh= 7448 Pa

Halfway up to the top of the spray: This is where I'm stuck, I tried using the equation (Pressure at halfway) = (pressure in the hose) - (1/2)(0.76 m)(1000 kg/m^3)(9.81 m/s^2) = 3724 Pa which is wrong. What am I doing wrong? Can anyone help with this part?

Explanation / Answer

Gauge pressure
= (0.85) * (1000) * (9.8) Pa
= 8330 Pa.
