WebAs shown in Fig. 6.2, with CT diameter 50.8 mm and length 2100 m, both the surface pressure and the frictional pressure loss in CT increased with the growth of flow rate. When the flow rate was 0.6 m 3 /min, the frictional pressure loss in the spiral pipe of CT was 10.95 MPa. As the flow rate increased to 0.8 m 3 /min, the frictional pressures loss … WebCalculating fire hose friction loss can be done using mathematical formulas. A common formula for calculating friction loss is this: FL = C * (Q / 100) ^2 * L / 100 Where FL = Friction Loss in PSI, C = friction loss Coefficient (or friction loss factor), Q = Flow rate in GPM, and L = hose Length. portable butcher block kitchen island https://torontoguesthouse.com
