What is the length of a cube formula?
Explanation: The number of square units in the surface area of a cube is given by the formula 6s2, where s is the length of the side of the cube in units. Moreover, the number of cubic units in a cube’s volume is equal to s3. Subtract 6s2 from both sides.
What is the characteristic size?
For example in a system of bound charges, the characteristic size would be the maximum distance between any two charges in the system as this tells us how far away we have to be from the system in order for a certain order multipole expansion to be valid.
What is characteristic length of pipe?
For pipe flow, the characteristic length is taken as D (diameter of pipe). For the free surface flow like channel flow, it is taken as hydraulic depth (R = A/P; A being flow depth and P being wetted perimeter). Thus, for free surface flow in a circular pipe, it is D/4 and y (water depth) for wide rectangular channel.
What is characteristic chamber length?
The characteristic chamber length is defined as the length of a rocket of the same volume would have if it were a straight tube and had no converging section… (He then shows the same equation you do in the question). Here the chamber is considered to include all the volume up to the throat area….
What is the length of a cube with a volume of 125?
5
All the edges of a cube have the same length, and the volume of a cube is the length of an edge taken to the third power. So the length of the edge of a cube with a volume of 125 is 5.
What is characteristic length in fluids?
The characteristic length is the dimension that defines the length scale of a physical system. This implies that for any system, which my contain several length scales, there may only be one characteristic length scale. This is also generalizable to the other characteristic scales such as time, speed, etc.
What is characteristic length Reynolds number?
Normally it is a length used in determining dynamic similitude. For instance, the ratio between inertia and viscous forces called Reynolds number depends on a characteristic length used to compare experimental data determined in similar situations. In pipes normally it is the diameter of the pipe.
