    Gas impingement flux, problem in substituting constants

    Homework Statement gas impingement flux density is given by ∅=P/\sqrt{}2mkT where m- mass of a molecule show that ∅=3.513*1022P/\sqrt{}MT where pressure in torr and M-molar mass of molecule then ∅ in molecules per cm2 per second Homework Equations ∅=3.513*1022P/\sqrt{}MT...

    Isospin and quark model, why isospin is not considered in quark model

    thanks a lot. could you explain me how the isospin is related with flavour in L=0 state? if isospin part is symmetric then what about flavour?

    Isospin and quark model, why isospin is not considered in quark model

    please explain some thing more than that. and the total wave function of baryons should be anti symmetric under the exchange of particles(fermions), then the combination of spin part and flavour part should be symmetric because color part is anti symmetric and spatial part is symmetric (note...

    Isospin and quark model, why isospin is not considered in quark model

    Homework Statement why the isospin wave function was not considered in quark model? only the others (flavour, color, space, spin) are considered? Homework Equations The Attempt at a Solution
