Friction loss is when the water inside the hose rubs against the inner lining and losses velocity as it reaches it destination. So when water is pumped through a hose it losses speed b/c of it rubbing against the inside of the hose. AKA Friction Loss b/c rubbing is another word for friction.

What are the four fundamental rules governing friction loss in hose and pipe?
See frictionlosscalculator.com. They have a good description of friction loss I fire hose.
What is the fire hose friction loss per 50 ft and 100 ft?
Friction loss is one of the things we use that's critical when pumping a fire truck with crosslays/hose off the truck. The most common formula runs off 100ft sections in the following size/FL format: 1.75 hose (crosslay/jump line): ~13.5 PSI loss per 100' section 2.5" hose (blitz line): ~18 PSI loss per 100' section 5" hose: .08 PSI loss per 100' section All rates are based on your typical flow rate in GPM's...however the more gallonage the more friction loss. There is an accepted standard for GPM and friction loss: 1.5" hose 100GPM at 30PSI per 100' 1.75" hose 150 GPM at 32 PSI per 100'
Fire hose friction loss per 50 ft?
unfortunately, you have not given enough information for someone to answer the question. What is the size of the hose, how many gallons are you pumping through it?
Which as more resistance a garden hose or a fire?
Difficult to say. Hydraulic resistance is proportional to diameter as well as length and velocity. Water moving very slowly in a short length of either type of hose would have negligible resistance. The more likely answer you want is that high-velocity water in a garden hose would experience MUCH more resistance (friction loss) than that in any fire hose of larger diameter. The actual numbers will depend upon specific friction-loss factors, including the type and size of hose and the gallons per minute. For example, the friction loss coefficient in a 1.5-inch fire hose (24) is more than ten times what it would be in a 2.5-inch hose (2.0) and 100 times that of a 4-inch hose (0.2).
How do firefighting use math?
Firefighters use math when calculating things such as friction loss in hose lines and pump pressures when operating at a fire. Many firefighters are cross trained as paramedics, and use math to calculate I.V. fluid drip rates and drug dosages.
How did the friction take longer time to fill water can with hose than tap?
Friction between water and hose slows the water.

What is the NFPA definition of what is the maximum distance a fire department connection can be from a fire hydrant?
The FDC and hydrant aren't something that connect directly together. In order to put any kind of water pressure into a sprinkler system, an engine HAS to pump it in. Therefore, as long as the fire apparatus has enough hose, or can GET the hose from other apparatus the hydrant could hypothetically be a block away. There may be problems with friction loss with any large distances though. In my local area, the fire department has a maximum of 150 feet from the FDC to the Fire hydrant.
