I guess what's sticking me is that I'm not sure what to consider and what to ignore. I imagine I need to consider the friction, yet ignore the mass of the water in the 2.998km of pipe and only consider the mass of the water in the upturned ends. However, because I'm also forcing water down on...
Let's say he needs to displace the water by moving the plunger 1/2 meter in 10 seconds.
I see one of the discrepancies is that I said 1.25cm diameter yet I was dumbly plugging that in as radius.
Would friction in this scenario be minimal enough to discount? Over 3km, it seems like friction might play a large role through the horizontal length of the pipe.
I understand why moving faster would require more force, but there are some other things I don't understand. For instance, wouldn't we use the formula for volume of a cylinder to figure out the mass of the water? (V = pi*r2h) If that's the case, wouldn't it be V = 3.142 * 0.01252 * 3000 =...
I'm writing the third in a series of Young Adult Sci-Fi/Fantasy novels, and I'm trying to calculate how much force would be required in the following:
Imagine a pipe that is 1.25 centimeters in diameter and 3000 meters long. The pipe lies perfectly flat, but a meter of the pipe at each end is...
