Definition: for a fluid with laminar flow in x-direction, thus for which vy = vz = 0 and vx = vx (z) ≥ 0, where x, y, z are Cartesian coordinates, scalar quantity characterizing internal friction and equal to τ xz d v x /dz MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaamaalaaabaGaeqiXdq 3aaSbaaSqaaiaadIhacaWG6baabeaaaOqaaKqzafGaaiizaerbc92B RbsqUrxAXvxyaGqbcOGaa8NDamaaBaaaleaacaWG4baabeaakiaac+ cajugqbiaacsgacaWG6baaaaaa@488B@ , where τxz is the shear stress in the fluid
