Water flow to an aerial....
Need some help understanding why you would feed identical aerials, with 2 different supply lines.
I was out of state visiting a friend that is also a fire mechanic, when he got called out for some problems with a fire truck. He asked if I wanted to go, and I said yes. When we got on scene, I noticed that one engine was feeding one aerial with a 5" LDH, and yet saw another engine feeding its twin through a wye with 2 2-1/2 lines.
The only difference between the two engines, is the one feeding with the 5" LDH was also shooting water through its deck gun. Both engines had the same number and sized handlines out flowing water.
Wouldn't there be a difference in flow rates through the monitors on the tip of the ladders with the different lines hooked up, or does it matter??? If it matters, both monitors were the same on the ladder.
