Re=2vˉrρηR e=\frac{2 \bar{v} r \rho}{\eta}Re=η2vˉrρ wherevˉ\bar{v}vˉis the average speed of the fluid, 𝜌 is its density, 𝜂 is its viscosity, and 𝑟 is the radius of the pipe. Previous Topic: Ideal vs Real Fluids...
He found that sound fills a reverberant room in such a way that the average energy per unit volume (i.e., the energy density) in any region is nearly the same as in any other region. The amount of reverberation depends on how much sound is absorbed by the walls in each reflection ...
The International Space Station travels at an average speed of 28,000 km/h or 17,500 mph. In a single day, the ISS can make several complete revolutions as it circumnavigates the globe in just 90 minutes. Placed in orbit at an altitude of 350 km, the station is visible to the naked...
Eqs. (A.12) and (A.13) can be described as the two forms of the spatial averaging theorem for layered porous media and are used for the derivation of the macroscopic equations. A.3 A new temporal averaging theorem The temporal averaging theorem relates the spatial average of a time deriva...
Equations of Motion | Overview & Examples from Chapter 9 / Lesson 1 60K Understand the concept of motion. Learn how to solve equations of motion in physics, specifically, equations for average acceleration and average velocity. Related to this QuestionWrite...
This expression is valid for monochromatic operation while in the modelocking regime the field f is a superposition of modes of different frequencies and then D is time dependent in general. However D can be split into its average value over a modulation period, D¯, and a remainder, which...
2. A person travelling on a straight line moves with a uniform velocity v1 for some time and with uniform velocity v2 for the next equal time. The average velocity v is given by,As velocity is uniform in both cases.So, we can write that d1=v1t where d1= Distance travelled in the...
If the dogs are identical, after a long period of time, it is expected that each dog will have on the average N/2 fleas. This will be true even if all the fleas originally resided on only one dog. However, if one waits a much longer time, all the fleas will be back on the ...
Not satisfied with the explicit scheme presented earlier, Yuste (2006) proposed a modification of weighted average methods for ordinary diffusion equations with an accuracy of order (Δx)2 and Δt to fractional-order diffusion equations. However, for the fractional version of the Crank-Nicholson me...
Science: They model phenomena such as population growth, radioactive decay, and chemical reactions. For instance, the half-life of a radioactive substance can be determined using logarithmic equations. Engineering: Logarithms are used in signal processing, acoustics, and electrical engineering. For exa...
