The solution for NCEES Sample Question #537 shows the formula as Erms = SQRT(k*T*R*delta f).
The formula in the EERM (Camara, 6th edition, page 42-2) is
Erms = SQRT(4*k*T*R*delta f). I do not understand why there is a difference of a factor of 4 under the square root. Can anyone explain this to me?
