waterlevels due to the increasedpressure is independent of thecross section of the U-tube,therefore we can consider itscross section to be 1 squareinch. A pressure of 14.7pounds to the square inchholds up a water column33.57 feet in length. Fromthis equivalent, calculate thepressure in pounds per… … Fig. 27. MEASUREMENT OF GAS PRESSURE 73 a mercury column 30 inches in length. From this rela-tion, calculate the pressure in pounds per square inchwhich is equivalent to the observed barometric reading. Adding the effective pressure to the atmospheric pres-sure gives the total pressure of the gas,…
