If 57,000 J of energy are used to stop a 100-kg object in 10 m, determine the coefficient of kinetic friction. For Effective Nuclear Charge, I'm confused about why the electrons would want to get closer to the nucleus? What's the pu...
I don't know how useful this is, but the maximum theoretical power extractable from air passing through a turbine of cross-sectional area , with initial speed , is , where the coefficient is the Betz limit. In a steady state (constant rotational energy of turbine), I suppose you could se...
a—the coefficient of friction between the tires and the road surface. The braking distance is closely related to dynamic characteristics the vehicle and the response time of the system. Taking into consideration the dependence described above, the braking distance relative to the vehicle speed was ...
To determine the head loss coefficient ξ of the studied racks, Kirschmer [24] proposed the formula 𝜉=𝑘𝐹(𝑠𝑏)43sin𝛽,ξ=kFsb43sinβ, (1) where kF is the bar shape coefficient. Since then, many researchers have conducted experiments to assess the hydraulic losses of ...
(head loss coefficient, internal flow) (1) (2) (3) In order to have a common form, the friction factor, f, for a pipe or channel of length L can be converted into a K-value by multiplying f by L/Dh, so that then, with (−dp/dx)L = ∆p, Equation (3) also holds for...
considering that it was a field verification test for the soil penetration resulting from the drop of an anchor pile. The coefficient of variance for the three test results was computed to be 2.28%, 2.32%, and 3.14%, and an international test standard regarding the soil penetration required th...
