Determination of K

Case Study II: Cylindrical Geometry Sudden Contraction Hentrance:Hexit = 3:1, Re=0.001, _=1.

• From simulation, _ptotal = Ktotal= 87.7;

• Using simplified Eq. of Motion:

_ptube= Ktube= 80+1.0=81.0;

• _pcontraction= Kcontraction=87.7-81.0=6.7;

• Since _=1, U1= 0.5[1-(y2/1.52)], _

_p=1.0

_p=80.0
