And extraterrestrials are most likely to evolve on worlds with higher air density
, slower orbits and more continents.
By boosting the air density
of the entire engine, marine turbochargers enhance overall output power.
DeChambeau, who considers such variables as air density
and elevation change in his pre-shot routine, went over his allotted time on No.
The eminently flammable batteries were air-cooled to reduce weight, while the lower air density
at high altitude meant the car would perform differently.
where [rho] is the air density
, kg/[m.sup.3]; f is the Chezy-Darcy coefficient of friction; Per is the airway perimeter, m; v is the air velocity, m/s; A is the area, [m.sup.2]; L is the length, m.
where [F.sub.rheo] is the rheological force, z the axial direction, [[rho].sub.a] the air density
, [[rho].sub.f] the polymer density, V the fiber velocity, [V.sub.a] the air velocity, g the gravitational acceleration, and [C.sub.f] the air drawing coefficient.
Finally, Dumas commented that the electric vehicle is a good match for the mountain because "the power remains constant" despite the decreasing air density
over the course.
The amount of energy that can be captured from moving air is a function of wind speed, wind collector area (called the swept area), and air density
. You can calculate the wind energy available at a particular site with a particular machine yourself, but be sure to stick to one set of units--metric or imperial--when working with formulas.
That altitude maximizes the efficiency of engines and keeps turbulence to a minimum as air density
is much lower that far up.
