Hey I've been working on this pressure problem, and I am really stumped. We just started fluids, and I'm not really sure where to start. If someone could help me or point me in the right direction, that'd be great. Thanks! Heres the problem: A straight horizontal garden hose 43.0 m long with an interior diameter of 1.50 cm) is used to deliver 20C water at the rate of 0.510 liters/s. Assuming that Poiseuille's Law applies, estimate the pressure drop (in Pa) from one end of the hose to the other. Like I said, I'm not even sure where to start.
