To measure gas flow, a narrowing is created in the gas pipeline and the pressure difference in the wide and narrow parts is measured (Fig. 19.3). Determine the gas flow rate if its density is 1.4 kg/m3, the pipeline diameter is 50 mm, the narrowing diameter is 30 mm, and the pressure difference is 18 mm of water column. Neglect the compressibility of the gas.
