Angle for maximum height using water streamDate: Wed Dec 07 15:04:46 1994 From: 12 tmu Subject: angle for maximum height using water stream I am trying to investigate the relationship between the angle a hose would have to be positioned in order to maximize the height of the stream of water of constant pressure. Contact me at Westminster High School, Westminster, CA (714)893-1381, Jerry White.

This question basically boils down to vector algebra, the way I see it. See, when you send a projectile flying, its motion has a horizontal component and a vertical component. For instance, it might start out with a vertical velocity of 6 meters per second and a horizontal velocity of 3 meters per second (how fast would this stream of water really be moving?). The horizontal component of the velocity won't change as the projectile moves along its path. But the vertical velocity will be affected by gravity, and the velocity will change at the rate of about 9.8 meters per second per second. The actual numbers aren't important, though, if you just want to find out the angle to hold the hose at. See, you want to maximize the vertical component of the velocity, so point the hose straight upward. That way, the water will have the greatest vertical velocity, and it will go the farthest up before it gets dragged back down by gravity. I hope this helps you. -Ken "Dr." Math |
