I am trying to evaluate the value of the expression but Mathematica is not giving the numerical solution. It is keeping some of the variables as it is i.e without passing the value which i am intending to pass. Can anyone help me out?
xo - 1/(96 Dh R re T \[Mu]^2)
po^2 (-1 + 96 C2 kno^2 Log[p[x]/po] +
1/po^2 2 Dh^2 R re^2 T \[Mu]^2 \[Chi] (-Log[p[x]/po] +
24 C2 kno^2 (-1 + po^2/p[x]^2) + 12 C1 kno (-1 + po/p[x])) +
p[x]^2/po^2 + 24 C1 kno (-1 + p[x]/po))
y /. {C1 -> 1.466, c2 -> .9756, c1 -> 1.466, C2 -> .9756,
H -> 75*(10^-6), \[Mu] = 1.78*10^-5, \[Chi] -> 1.3, R -> 287,
T -> 300, re -> .0979, Dh -> 2*H, kno -> .068, po -> 641.7729,
y = .3*H, xo -> 25*Dh, p[x] -> 800}
