Abstract: In the paper , twoOphase stratified laminar flow law in pipe was established with fluid mechanics NOS equations. The coupling conditions of the two phase interface was set up the fluid mechanics analysis of the two phase laminar interaction and the mathematics equations of the two phase stratified flow and the flow law was obtained the transportation of hight viscidity fluid
easily comes true by the application of the stratified flow principle.

Key words: flow in pipe, stratified flow, mathematical model, pressure drop.
