Question: How to solve the BVP and draw a 3 D plot for skin fiction and nusselt number

eq1 := diff(f(eta), eta, eta, eta, eta)+(2*f(eta)*(diff(f(eta), eta, eta, eta))+2*g(eta)*(diff(g(eta), eta)))*(1-phi)^2.5*(1-phi+phi*rhos/rhof)-sigmanf*M*(diff(f(eta), eta, eta))*(1-phi)^2.5/sigmaf = 0

eq2 := diff(g(eta), eta, eta)-(1-phi)^2.5*(1-phi+phi*rhos/rhof)*(2*(diff(f(eta), eta))*g(eta)-2*(diff(g(eta), eta))*f(eta))-sigmanf*M*g(eta)*(1-phi)^2.5/sigmaf = 0

eq3 := k[nf]*(diff(theta(eta), eta, eta))/(Pr*k[f])+((1-phi+phi*rhos*cps/(rhof*cpf))*2)*f(eta)*(diff(theta(eta), eta))-4*lambda*(1-phi+phi*rhos*cps/(rhof*cpf))*(f(eta)^2*(diff(theta(eta), eta, eta))+f(eta)*(diff(f(eta), eta))*(diff(theta(eta), eta)))+sigmanf*M*Ec*((diff(f(eta), eta))^2+g(eta)^2)/sigmaf = 0

eq4 := (1-phi)^2.5*(diff(chi(eta), `$`(eta, 2)))+2*Sc*f(eta)*(diff(chi(eta), eta))-sigma*Sc*(1+delta*theta(eta))^n*exp(-E/(1+delta*theta(eta)))*chi(eta) = 0
