Flow k factor
WebMany sprinklers are rated with a K factor that describes their performance. This is defined as: Q = K √ (P) Where: Q = Flow rate (US gpm or l/min, K has units of US gpm/psi 0.5 or l/min/ (bar) 0.5 depending on the published literature. The K factor for sprinklers is NOT the same as a fitting K factor (which is used with a velocity2 element to ... WebOct 30, 2024 · To find the K factor, simply refer to the information found in either a graph or chart format in the specifications of the VAV box (the chart includes the calculations of the area and Amplification factor). The K factor is the point at which the size of the box, shown in inches, converges with the maximum airflow at 1"w.g. velocity pressure (on ...
