A crease resist (CR) agent is applied by padding to a fabric with a 1 m width and a 200 g/m² areal density. The concentration of the CR agent in the pad bath is 100 gpl, and the fabric speed is 50 m/min. The expression is 110%, and the specific gravity of the pad liquor is 1.1. What is the rate (in kg/min), accurate to one decimal place, at which the CR agent needs to be added to the bath to maintain the bath concentration?
