Damping coefficient for viscous fluids?
The damping coefficient ς is a parameter which determines the behavior of the damped system
The damper coefficients in jounce and rebound are significantly different Why is this a good design feature?
In a normal race car sort of setup, you want to have the shocks compress at a lower coefficient than rebound, This is because you want the shocks to be able to rebound back into their natural position as fast as possible and be able to hit the next bump that it will see. In eng terms you want to minimize the time that you see a transient response from the shocks. Typically you'll see the rebound is 2 to 3 times the compression coefficient.
How much speed of wind is required to move 1 Kg?
No simple answer - it depends on the item's surface area and its aerodynamic coefficient. Easy move - a ten square metre sail will move a small boat in a light breeze. Hard move, a square block of uranium on a checkerplate floor. More info will help.
How can we calculate the weight of iron plates?
If actually weighing the plates is impractical, you could try hanging the plates from a spring, and testing to find the spring's k value, and recording the displacement of the object while hanging from the spring, and use that to calculate the force on the plate, which equals mg. if the density is known, you could immerse the plates in something to find their volume and then calculate their weight from that. or, you could try and pull them with a force meter, taking two data points so that you can solve for the both the friction coefficient and weight.
What is the Hazen Williams equation?
There are different ways of writing the hazen -william friction loss equation depending on which system of units you are working with. If you want to calculate friction loss in feet then the equation is as follows:hL = ((L)/(((6.27*10^-4)*C*D^2.63)^1.85))*Q^1.85Where:hL = Headloss (ft)L = Length of pipe (ft)C = Hazen William coefficient for the material that the pipe is made out of (unitless)D = Diameter of the pipe you are working with (in.)Q = Flow rate you are working with (cubic feet per second (cfs))
