Flow Regime Determination

Two Phase Flow Regime Determination

Important Notice:

	The two phase flow regime determination procedure presented here applies to steady-state, isothermal two phase pipe flow of incompressible Newtonian fluids. The procedure is based on Baker's flow regime maps.
	For your convenience, The input form below has several multiple choice fields {using radio buttons} with one field already selected as default. Please make sure that you always mark the proper button corresponding to your input if it is different from the default.

Report:
Flow regime and include

Not required if both vapor and liquid flowrates are specified in terms of mass velocity.

For commercial steel pipes only.

The schedule list is all inclusive. Hence, some of the pipe schedules shown are not available for every nominal pipe size. If you select an invalid nominal pipe size and schedule combination, the server will return a list showing which schedules are available for the nominal pipe size you specified. We apologize for this awkward behavior but it is due to current HTML and browser technology limitations.
