the equation 2500 ft.3jlb.·mol = ae50b where 50 is the expression
for altitude in thousands of feet. Similarly, at 70,000 feet~
6450 =ae70b, and by solving to eliminate a, we find 2.58 = e Ob
or 20b = .95, and the constant b is equal to .0475. Thus, the
equation may be written:

y was originally defined as the molar volume, equal (for 98% helium)
to:

From this relationehip, we may solve for

Differentiating with respect to W:

We see that the value of the constant a is unimportant here, and
the expression is independent of balloon volume, as long as it
does not var/ with time. Included is the assumption that over a
short period of ti~e buoyancy of lifti~gas does not change.
Thus, we have an expression for A, the altitude sensitivity, which
is valid between 40,000 and 105,000 feet. Similarly, it is possible
to evaluate altitude sensitivity for operation between 0 and 30,000
feet. A in this range is equal to 31,400 ft./lb.
