If the diameter of the pipe is the same throughout, find the height at which the tank is located. Atmospheric pressure may be assumed as 1.0 * 10^5 Pa and G as

The gauge pressure in a garden hose is 2.0 atmospheres. If the cross-sectional area of the hose is 4.0 cm^2 and the nozzle output area is 0.4 cm^2(cm^2= 10^-4m^2): (a) How fast does the water leave the hose? (b) If the hose is held parallel to the ground and is 1.0 m above the ground, how far out will it travel before it hits
