Description

Square law graph paper with a maximum pressure of 10 bar and maximum Flow of 500 L/min

Square law graph paper with Pressure (bar) on a linear Y axis and Flow (L/min) on a square-scaled X axis (proportional to Flow²). Used for calculating the Maximum Flow Demand (Qmax) of a sprinkler system, since plotting pressure against flow² produces a straight line for the system's hydraulic characteristic.
