Okay, I really am out of options here. I have been up and down the Bernoulli equation, and I can't get this problem to save my life. Will someone please help me figure this out. I'm beyond confused.
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 0.54 m.
What is the pressure inside the hose?
Okay, so, I went and derived the equation P = (rho)(g)(h)
and P = (1000 kg/m^3)(9.81 m/s^2)(0.54 m) = 5292 Pa
NOPE. I'm being told this is wrong and need to redo this. So, I thought, "Oh, wel maybe this is in the wrong units; perhaps this is atmospheres (which didn't make sense because THAT WOULD BE HUGE!) But I converted anyway by 5292/101325 = 0.0522 Pa?
Wrong again. What's up with this problem?
