18. To analyze the squeeze film damping effect of MEMS plates with raised strips, an analytical solution is given to calculate the coefficient of squeeze film damping by using Reynolds equation and the first boundary conditions. 针对带有凸条平板的MEMS结构压膜阻尼效应,利用基本Reynolds方程和特定的第一...
Under steady flow conditions, the continuity equation is simply d(uy)/dx=q, and the momentum equation becomes (4)S0−Sf−quy=d(y+u2/2g)dx which is used to calculate the water surface profile in an open channel where an obstacle impedes the flow. Standard techniques could be employed ...

The primitive equations are identical to those used to develop the coastal Kelvin wave phase speed solution (U-momentum, V-momentum, and continuity equations) and the motion is unidirectional and parallel to the Equator. 该波动的原始方程与推导海岸开尔文波相速度的方程一致(U向动量方程及连续性方程...
How to Use Nernst Equation Example Example 1: The following example shows how the Nernst equation may be used to calculate the potential of an electrochemical cell at non-standard conditions: An electrochemical cell is set up at 298 kelvin with the balanced reaction 2Al(s)+3Fe2+⇌2Al3++...
If the pipe is conveying oil which has a density ρ of 900 kg/ m3, calculate the magnitude and direction of the resultant force on the bend when the oil is flowing at the rate of 0.5 m3 /s. The bend is in a horizontal plane Here’s the...
To calculate a motional EMF, use Faraday's law for the production of an EMF, e = - dB_flux/dt where e stands for motional emf, dB_flux is the change in the magnetic flux, and dt is the change in time. The motional EMF will be the opposite of this EMF. What did Lenz's law ...
