hiiiii thanks for ur help and sorry for late response, Topher925 u may be right...this is real problem... but i know only inlet conditions ...don't know the outlet conditions...then how to apply this equation? if assumed outlet dia, then i am able to calculate velocity at outlet...but again...

hii , i know the inlet conditions i.e. dia 2mm , pressure = 100 bar, density= 0.001176 m3/kg, mass flow rate remains constant= 0.09017 m/s , for same mass flow rate for pressure drop 80 bar(i.e. pressure at outlet is 20 bar) for COMPRESSIBLE FLUID what will be the outlet dia? take fluid carbon...

thanks for advice stewartcs, actually i want to know design procedure (that should include formulae) to design expansion valve for refrigerants...e.g. say for R22 for specific pressure drop ...how to design expansion valve...how to fix the diameters of valves...

:!) anybody knows @ design of thermostatic expansion valve used in refrigeration and air conditioning.....?

how to calculate head loss due to sudden enlargement in case of compressible fluid? hiiiiii guys, am graduate student, i want to know @ head loss in case of compressible fluid due to sudden enlargement...pls help me ...as soon as possible...
