Vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or
Saturated Adiabatic Lapse Rate
The lapse rate is defined as the rate at which atmospheric temperature decreases with increase in altitude. The terminology arises from the word lapse in
Power (aerodynamic drag)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force
This formula calculates the duration of propulsion system burn which is required to achieve a desired ΔV.
Thrust to Power
Thrust is a reaction force described quantitatively by Newton’s second and third laws.
The power needed to generate thrust and the force of the
