We work for Cola Company and there have been some discussions onwhich pressure setting is best for filling out bottles. If weoverfill the bottles then we are spending money we do not need to.If we are under filling the bottles we run the risk ofdissatisfaction of the customers. If we can fill the bottles usinga higher psi we can run the line faster and thus increase ourproduction. Our current fill pressure is 25psi. Management wants toknow if there is a different variation from the standard betweenthe two pressure settings.
ml (25psi volume): 1007.2, 1008.4, 1010.2, 1011.2, 1008.0,1009.0, 1011.4, 1013.4, 1010.6, 1010.9
ml (30psi volume): 1001.2, 1003.1, 1003.6, 1001.4, 1002.7,1004.3, 1002.6, 1005.0, 1003.7, 1004.4
