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.
