Suppose a water-gage reading of inch on a 1-inch pipe at 60° F. and poundsper square inch, the specific gravity of the gas being From the table on page 39 the cubic feet of gas per 24 hours is found to be 20,568. Ifthe more exact formula be used, the quantity of natural gas per 24 hours is found to be21,824. The difference is 1,256, or per cent. These three examples will serve to show the errors involved in gasmeasurement by means of the Pitot tube when the static pressure ofthe gas is not measured. As regards the measurement of a gas flow on a lease for the purpose of determiningthe quantity available for gasolinemaking, the use of the more simpleform of Pitot tube appears to besatisfactory. 100 95 H M §90 2 a< ft oq ws ft 85 80 75 70 65 60 GENERAL COMMENTS ON USE OFPITOT TUBE. 55 WEIGHT OF WATER IN POUNDSPER CUBIC INCH Fi
