Pentium PC running Windows 95 with Labtech Notebook Pro Windows based data acquisition software using a Metrabyte DAS-8 analog to digital data acquisition board.

Compare the performance of separator number in co-current flow with the same separator in counter-current flow at various pressures and flow rates. For one of these arrangements, determine the time necessary to approach steady state at the different pressures and flow rates.
