How long will the pump run, which can transfer 40 liters of water per minute, to fill a tank 2 m long, 80 cm wide, 1200 mm high with water?
These tasks: W (capacity of the pump used) = 40 l / min = 0.04 m3 / min; L (tank length) = 2 m; B (tank width) = 80cm = 0.8m; h (height) = 1200 mm = 1.2 m.
To determine the operating time of the pump used, we apply the formula: t = V / W = L * B * h / W.
Let’s perform the calculation: t = 2 * 0.8 * 1.2 / 0.04 = 48 minutes.
Answer: The pump used will run for 48 minutes.
