It has nly 6 digits

I am doing my undergrad in mechanical engineering and I have been using this book for CFD self study and got as far as simulating Couette flows(not much, I know). Is there any book or internet resource where I can find more basic simulation problems and info on solver development? Thanks!

What is the concept behind it?, why should coefficient of restitution be 1 for elastic collisions, can it be derived in some way?

I have only two,the 4 variables are the x and y components of each of the particles, is using the KE balance same as using the restitution formula with e=1?, From where does the law of restitution come?, it is not a fundamental conservation law, so what is the principle behind it?. And while...

The problem is like this, i have the initial velocities and masses, i want to find the final velocities. I have assumed elastic collision , so i have 2 momentum equations and an energy equation. But i have 4 variables, I have not used the restitution formula, because i have assumed elastic...

When considering the case of two or more point masses colliding in a 2 dimensional plane, is there any way to determine the final state completely from the initial conditions? if not is it not a blow to the deterministic ways of classical physics...

Hi, I was trying to learn a bit of quantum mechanics from Feynman lectures. In the 3rd volume of the Feynman lectures, he talks of the double slit experiment with electrons. He says that if we keep a light source near the first slit, so that every time an electron passes it scatters light and...

Hi,I don't understand the holographic principle,how can the entire physics in a space be done on its boundary,arent we supressing a dimension and there by losing the information contained in it?,and is it neccesary that the boundary be closed?

if its a postulate then what motivates it?

i have been trying to learn a bit of quantum mechanics,this is some thing that has been bothering me , if the states of a system can be expressed as vectors in the Hilbert space,what is the motivation behind saying that physical observables can be given by operators?even then ,how can we say...

hi, i was tryin to learn some relativistic particle dynamics and came across reltivistic force m\frac{d^{2}x}{d\tau^{2}},how does this help in transforming forces between reference frames?i dnt understand how this wrks since the vale of velocity changes with time

so that means all rotations are proper lorentz transformations while reflections are not,but won't reflections change the proper time,\tau,so all reflections can't be lorentz transformations ryt?

the -0.273109F u got is m1-m2,and u used it as m2-m1 to find the acceleration.its just a careless error noting more

what does it mean by "any \Lambda^{\alpha}_{\beta} that can be converted to the idendity \delta^{\alpha}_{\beta} by a continuous variation of parameters must be a proper lorentz transformation"?
