Hi
Can anyone tell me anything about these numbers. I know the formulae I just want a qualitative description.
As far as I have it the Rayleigh number tells you if you can have convection and how vigorous that convection is, and the Nusselt number tells you how efficient that convection...
When constructing a Rayleigh Refractometer the formula for the refractive index of a gas at pressure P and temperature T is:
mu(P,T) - 1 = (gamma) P/T
where,
mu(P,T) = refractive index as a function of pressure and temperature
and
gamma = [n(lambda)Ta]/[L(deltaP)]
where,
n = fringe...

I am to derive the incorrect Rayleigh-Jeans formula from the correct Planck formula to show why plank's constant does not appear in the Rayleigh-Jeans formula. I should also recall the Stefen-Boltmann Law
here's what I have but I'm stuck...
Rayleigh-Jeans formula: u(\lambda)=\frac{8 \pi k...
Use the Rayleight quotient to find a good approximation for the principal eigenvalue of the Sturm-Liouville problem.
u'' + (\lambda - x^2)u = 0
0 < x < 0
u(0) = u'(1) = 0
Any help?
A simply supported beam of negligible mass , length l and stiffness EI carries a concentrated mass m at its centre. Apply Rayleigh' s method to find the beams frequency of small oscillations.
Isn' t it just give byt this with rowe replaced by m?
i think I've posted this topic in the wrong thread(theoretical physics).. anyways, i would like to ask, if anyone could give me some backgrounds on Rayleigh Dissipative Function.. thank you very much in advance..
Physics people,
what is the theory behind the Rayleigh Dissipative Function? could you kindly give me some website which could help me understand this?
