Based on the given scenario, the rate of increase in water pressure in atm/km is known to be 992 atm/km.
<h3>What is water pressure?</h3>
Pressure is known to be that kind of force that is known to often pushes water via pipes.
Note that Water pressure is a tool that is often used to know or identify the flow of water from any given tap. The amount of pressure at one's tap is said to be often dependent on how high the service tank or water tower is above one's home.
Therefore since 1 atm/m = 1000 atm/km
Hence 0.992 atm/m :
= 0.992 x 1000
= 992 atm/km.
Therefore, Based on the given scenario, the rate of increase in water pressure in atm/km is known to be 992 atm/km.
