A garden hose with a diameter of 0.66 in has water flowing in it with a speed of 0.65 m/s and a pressure of 1.0 atmospheres. At the end of the hose is a nozzle with a diameter of 0.25 in. (a) Find the speed of water in the nozzle. (b) Find the pressure in the nozzle. I found out the speed of the water, but I am not sure how to find the pressure. I tried using the equation P1+1/2 pv1^2=P2+1/2 pv2^2 and solving for P2 but the answer that I get is negative. I think the problem is that I'm not sure about what to plug in for p. I looked up the density of water and used that value (1000), but am I supposed to figure it out another way? Because the only other equation I found for density was m/v and I wouldn't be able to calculate that.
