Water level is 40 inch below ground level or -40 inch with respect to ground level after 20 minutes if sump is full of water and level of water decreasing 2 inches per minute
Given:
- A sump is full of water
- Level of water decreasing 2 inches per minute by a Motor
To Find:
- Level of water from the ground level after 20 minutes
Solution:
- Sump is under ground to collect desirable/undesirable liquids
- Top of sump is at ground level
Step 1:
Multiply 2 inch per minute with 20 minutes to find drop in water level in 20 minutes
Level Drop = 2 x 20 = 40 inches
Step 2:
As Sump is full of water hence initial level = ground level
Hence level of water from the ground level after 20 minutes is
40 inch below ground level
or -40 inch with respect to ground level.
The level of water from the ground level after 20 minutes 40 inch below ground level or -40 inch with respect to ground level.
