Abstract
Equations predicting cord length per hose pitch, weight per unit hose length, and percent inner-liner coverage for plain stitch knitted automotive heater hoses are presented. These equations help hose manufacturers to determine the reinforcement cost for knitted hoses. A spreadsheet using these derived equations plus a hose burst equation from the literature also offers insight into key cord physical properties for knitted hoses. Cord loop tenacity (loop break strength) falls out as a key element in controlling knitted hose burst pressure.
