You'd also need the bend to be sure that the tube wasn't acting like a "pitot tube" and giving you an anomalous high reading from the dynamic pressure associated with propellant flow velocity along the chamber. (Perhaps a tube with a capped end and small holes around the side, with the main tube oriented lengthwise so the flow would be past the holes instead of into them, would work best for this?) -dave w _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
