The Roswell Report: Fact vs. Fiction in the New Mexico Desert
USAF / The Black Vault · 1995 · 882 pages · text by OCR
The Roswell Report: Fact versus Fiction in the New Mexico Desert was published by Headquarters United States Air Force in 1995. The Black Vault distributes this copy. It reproduces the report by Col. Richard L. Weaver and the synopsis by 1st Lt. James McAndrew, both written after a General Accounting Office inquiry requested by Representative Steven Schiff. The Air Force search found no evidence of an extraterrestrial craft or crew. It concluded that the Roswell debris most likely came from NYU Flight No. 4, a Project MOGUL balloon train.

The ballast flow at any time, t:
$$
\frac {d W}{d t} = C _ {F} \rho_ {b} A \sqrt {2 g h}
$$
so that:
$$
\sum_ {t = 0} ^ {3} \Delta W _ {b} = \int_ {0} ^ {\tau} C _ {F} \rho_ {b} A \sqrt {2 g h} d t
$$
where:
C $ F $ is a coefficient of discharge, dependent upon Reynolds number of the flow through the opening
In this equation only $ \sqrt{2}g $ and A are constants (if temperature effect on the opening A is neglected), $ P_{b} $ is dependent upon temperature of the fluid and h is dependent upon the shape of the vessel containing the fluid and time t.
If ballast flow is controlled by atmospheric pressure:
$$
\sum_ {t = a} ^ {\dagger} \Delta W _ {b} = \sum_ {t = a} ^ {r} \frac {d W}{d t} + p > p _ {c}
$$
with a fixed valve opening (open-or-closed valve)
where $ ^{\dagger} \mathrm{p} > \mathrm{p}_{\mathrm{c}} $ represents the time when atmospheric pressure is greater than the pressure of control. Here, again, $ \frac{\mathrm{d} w}{\mathrm{d} t}=C_{F} \rho_{b} A \sqrt{2 g h} $ With ballast flow proportional to D=D
With ballast flow proportional to $ p-p_{c} $
$$
\sum_ {t = 0} ^ {\dagger} \Delta W _ {b} = \sum_ {t = 0} ^ {\dagger} \frac {d \left(\frac {d w}{d t}\right)}{d \Delta p} \left(p - p _ {c}\right) t _ {p > p _ {c}}
$$
where:
$$
\frac {d \left(\frac {d w}{d t}\right)}{d \Delta p}
$$
relationship between rate of flow and pressure difference ( p-p $ _{c} $ ) where $ p > p_{c} $
If we include a rate of pressure change control or a rate of ascent control such that there is no ballast flow if rate of pressure change is less than some value $ - \left( \frac{dp}{dt} \right)_{c} $ or rate of ascent is greater than some value $ \left( \frac{dz}{dt} \right)_{c} $ , we impose the condition for ballast flow in the above two cases that for flow to occur $ p > p_{c} $ , and $ \frac{dp}{dt} > \left( \frac{dp}{dt} \right)_{c} $ or $ \frac{dz}{dt} \left(\frac {d p}{d t}\right) _ {c}
