ubic feet perminute. or 2,056,564 cubic feet of gas in 24 hours. Using the same data but referring them to the approximate values given in the tableon page 39, one finds the quantity of gas to be 2,103,185 cubic feet in 24 hours. Thedifference is 46,621 cubic feet, or 2.3 per cent of the first value. Example 2.Suppose a water-gage reading of 0.3 inch on a 6-inch pipe at 60° F. and 14.65 poundsper square inch, the specific gravity of the gas being 0.6. Proceeding as in the first example, according to the formula: Q=(5773.68)X1963^j-fgl2 ©

Suppose a water-gage reading of 0.3 inch on a 1-inch pipe at 60° F. and 14.65 poundsper square inch, the specific gravity of the gas being 0.60. 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 5.8 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 0.0362 0.0361 0.0360 0.0359 0.0358 WEIGHT OF WATER IN POUNDSPER CUBIC INCH Fi
