// Heat transfer analog to Eqn. 3.12
// The Eqn. remains the same with the dimensionless conc. ratio replaced by ((tl-to)/(ti-to))
// The dimensionless group:
// eta = 2*Dab*L/(3*del^2*velocity);
// eta = (2/3)*(Dab/(del*velocity))*(L/del);
// Ped = Peclet no. for mass transfer
// eta = (2/3)*(1/Ped)*(L/del);
// For heat transfer is replaced by
// Peh = Peclet no. for heat transfer
// eta = (2/3)*(1/Peh)*(L/del);
// eta = (2/3)*(alpha/(del*velocity))*(L/del);
// eta = (2*alpha*L)/(3*del^2*velocity);
