<p>You forgot the most important part!</p><p>Friction loss calculations! I was taught by Chief Murphy (really that was his name) to pump ALL fog nozzles at 140 THEN do the calculations.</p><p>Math is HARD in the dark, while incoherent radio chatter is blaring, smoke is banked down to the ground (the wind always blows TOWARDS the pumper), and you are trying to manage multiple hand lines (always pulled off the other side of the truck from your panel so you can't see them) of varying lengths and a LDH supply line... And it's that house on Sunnyslope... (those that were there will get the reference)</p><p>It's been 20 years and IIRC you do the math for 2.5&quot; hose of the flow rate you desire, perform a conversion to the size line you have, with additions for any appliances and fixtures, for gravity and more. Q^2*L???</p>
