Решение задачи по физике раздел 30 пункт 23 механика

23. In order to determine the amount of pumping gas is an instrument based on the principle of action of the pitot tube. When pumping nitrogen through the pipe during t = 1 minute passes gas volume V = 59,3 m3. Determine the diameter d of the pipe, when the difference of water levels in the Pitot tube bends Δh = 1 cm. The density of nitrogen ρ = 1,25 kg / m3, the water density ρ1 = 1 g / cm3.
