How can I calculate the drag coefficient of an object? You can compute the drag coefficient using the drag force equation. To do so, perform the following steps: Take the fluid density where the object is moving. Multiply it by the reference cross-sectional area and by the square of the ...
So for example a rocket moving with speed of 100 000 km/s is creating an attractive force behind the rocked in line of its movement. This also applies for the rotating mass where we take the instantaneous speed of rotation and calculate the relativistic mass caused by speed. Yea, this is...
The Rocket Hovering Equation is calculated by equating the forces acting on a hovering rocket: the force of gravity pulling the rocket down, the thrust force pushing the rocket up, and the drag force opposing the rocket's motion. The equation is F = mg + T - D, where F is the net ...
In practice, no more than the n = 0 term is ever calculated, because higher-order terms are expensive to calculate and can never properly include the frequency-dependent effects of waves reflected and converted by regions of high spatial gradients in velocity and density. The review by Lambare...
For them, we need different equations that also take into consideration gravitational force. Newton's universe — arrive at the destination at full speed It's the simplest case because here, TT equals tt for any speed. To calculate the distance covered at constant acceleration during a certain ...
Instead, we have to obtain first the transformed value of ε and then calculate the new values of n from ε. For a given crystal symmetry, the refractive index can be represented by an ellipsoid known as the indicatrix (Rossi, 1959). When the x, y, and z coordinate axes are chosen ...
(7) and retains any dependence on p, one can no longer use the mobility to calculate the velocity as in Eq. (1). But, mobility in this definition would allow one to easily determine how the velocity of a grain boundary varies as a function of p. This dependence of velocity on ...

(9.95a) can be assumed to be in a complex form Z=Z˜ejωt with its complex amplitude, of which the real part is used to calculate the energy flow based on Eq. (9.93a). The solution of this equation is (9.95i)Z=1k{ωρfA(ϕ¯0M+ϕ¯M)sinωt−mlω2cosωt+(m+M...
The change in the drag force on the plate. b. The change in the rate of heat transfer between the fluid and the plate. Calculate these quantities if the velocities are tripled, assuming that the flow is still laminar. 5.7 Consider a cylindrical pin fin, 10 mm in diameter and 80 mm lo...
