eq1 := 285 = .3354101966*sqrt(1/(1.025384421*10^(-9)*d^4/t[min]^3+5.568148129*10^(-8)*d+(3/550400)*d^2/t[min]));

I would like to plot tmin for varying values of d.

i can solve for tmin with a know value of d using fsolve

but can't do the plot I want

I wrote the procedure below and i want to plot on one graph for the range lambda = 0 to 60 (x-axis),  beta = 0, beta = 5, beta =10, beta = 15, beta = 20 etc. 

in other words i want to plot Cp vs lambda at different beta values

Can any one assist me in doing this.

_______________________________________________________________________

Cplot := proc (beta, lambda)

local lambda0, Cp;

lambda0 := 0.22e-1*beta^2+(7/1000000000000000)*beta+5.6;

I have an equation that is a function of two variables i.e Cp(beta,lambda). I have to plot several Cp curves on the same graph for a range of lambda=0..15 (x-axis). The 1st curve I want Cp@beta=0, 2nd curve Cp@beta=5, 3rdcurve Cp@beta=10 .... and so on

How can I do this without having to define a separate Cp equation for each beta value?
