A submersible pump is put under the water at the bottom of a well and is used to push water up through a pipe. What minimum outp ut gauge pressure must the pump generate to make the water reach the nozzle at ground level, 71 m above the pump?
1 answer:
Answer:
695800 N/m^2 or Pa
Explanation:
Height of the water from the ground H = 71 m
Acceleration due to gravity g =9.8 m/s^2
density of water ρ= 1000 kg/m^3
The minimum output gauge pressure to make water reach height H
P= ρgH
= 1000×9.8×71= 695800 N/m^2 or Pa

Hey, can you state your question a little more clearly
I think it’s physical change, because the objects aren’t changing into another substance, just changing their physical shape. Hope this helps!
<span>when the gravitational forces and air resistance equalize on an object that is falling toward the earth and the object stops accelerating its called TERMINAL VELOCITY</span>
The answer here could be pressure vs. temperature.
