From the well, they pumped out 0.5 m3 of water with a pump, the work perfect in this case is equal to 30,000 dzh. what is the depth of the well?

These tasks: V (volume of pumped out water) = 0.5 m3; A (work done by the pump) = 30,000 J.

Reference values: ρw (density of pumped water) = 1000 kg / m3; g (acceleration due to gravity) ≈ 10 m / s2.

The depth of the well can be expressed from the formula: A = ΔEp = m * g * h = ρw * V * g * h, whence h = A / (ρw * V * g).

Let’s make a calculation: h = 30,000 / (1000 * 0.5 * 10) = 6 m.

Answer: The depth of the well is 6 m.
