Contra-rotating propellers offer increased efficiency by capturing the energy lost in the tangential velocities imparted to the fluid by the forward propeller ( known as " propeller swirl " ).
12.
The object moves to a lower orbit, and the orbit becomes elliptical, because it now has a tangential velocity that is too fast for circular orbit at the new radius.
13.
The circulation \ Gamma is the contour integral of the tangential velocity of the air on a closed loop ( also called a'circuit') around the boundary of an airfoil.
14.
Surface layers are characterized by large normal gradients of tangential velocity and large concentration gradients of any substances ( temperature, moisture, sediments et cetera ) transported to or from the interface.
15.
The swirling fluid enters the control volume at radius r _ 1 with tangential velocity V _ { w1 } and leaves at radius r _ 2 with tangential velocity V _ { w2 }.
16.
The swirling fluid enters the control volume at radius r _ 1 with tangential velocity V _ { w1 } and leaves at radius r _ 2 with tangential velocity V _ { w2 }.
17.
And it is precisely this tangential velocity that is too big to make the kinetic energy only half of the potential one if one calculates the potential energy from the gravitation of the visible galaxies.
18.
Any rotating body has components of a tangential velocity ( m / s ), a tangential acceleration ( m / s ^ 2 ), and a frequency ( m / s ^ 3 ).
19.
High tangential velocity of WISE 1828 + 2650, characteristic of an old disk population, indicates possible age of WISE 1828 + 2650 in the range 2 4 Gyr, leading to mass estimate of about.
20.
In order for a rod to fall straight toward the center of Earth it would need to be launched away from the station with a tangential velocity equal in magnitude and opposite in direction from the orbiting station.
