Ambient Pressure: P(mm-Hg) = 760–(2.50 x 50) = 635 mm Hg
Vapor Pressure of Water (at 298 °K): 23.9 mm Hg
Corrected Flow: F
corr
=150 x 298 x 760 x (635+23.9) = 189 cc/min
294 635 635
From the above computations, the exit flow rate should be set to 189 cc/
min. using an appropriate flow measuring device and the target respositioned
if necessary so that the float is centered within the target opening.
Subsequently, it should not be necessary to measure the exit flow unless
another circumstance, of the type listed above, occurs.
