The wellbore

The wellbore has a tributary of 2 m3 per hour. When there is no tapping, there are a stable 28 liters of water in the well. The pump suction basket is at the bottom of the well. At 14.00, the water was pumped out at a rate of 0.5 liters of water every second. What time will the water in the well be depleted?

Result

t = hh:mm (Correct answer is: INF) Wrong answer

Solution:

Q=2000 l/h Q1=Q/3600=2000/3600=590.5556 l/s Q2=0.5 l/s  Q2<Q1  V=28 l  x Q2=V+Q1 x  t=
