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?
It depends on flow. 2 PSI for 500 GPM 8 PSI for 1000 GPM 18 PSI for 1500 GPM 32 PSI for 2000 GPM This is per 100' ft If your flows are big, ie. defensive conditions, you must relay for anything over a couple hundred feet in length. Capt. Ridgeway Tumwater Fire

Assuming the buckets are identical... Hose 1 fills 1/45 per minute and hose 2 fills 1/30 per minute, so together in one minute they would fill 1/45 + 1/30 ie 5/90 or 1/18, ie the bucket would be filled in 18 minutes.
This will depend on where you live and the cost of water in that region. It will also depend on how hard the hose is turn on and how much water is running from it. For example, if the hose is spraying water at a rate of one litre per second, and the cost of water in your region is one dollar per litre, then it will cost sixty dollars a minute and a total of $3600 for the full hour.

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'
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).

yes Ice contain a lot of friction, enough to even set something on fire if a car is rubbing on it at 85,000 miles per hour.
1.03 gallons
Faster than a human can move. You would need to move several thousand miles per hour to create enough air friction to ignite combustible materials.
Hydraulic hose cost per meter depends on the gauge of hose desired, but as an example, 5/16" hydraulic hose can be obtained for approximately 3.48 British Pounds Sterling per meter. 1.3/16" hydraulic hose can be obtained for approximately 11.43 BSP per meter.
Yes, there is friction from movement through the air. The higher the speed of the train and the greater the surface area of the train impacting the air, the greater the friction, and hence the temperature, energy loss and limitations on speed. In the future we will integrate this technology with zero/low pressure tubes, made from carbon fiber or some other materials that will allow these trains to operate with little to no friction and therefore unimaginable speeds, theoretically tens of thousands of miles per hour, and at a fraction of the energy required to lift an airplane from the ground and withstand friction and energy loss at super sonic speeds. These trains will likely be built underground for a number of reasons and likely begin by transporting freight.
The gallons per hour that come out of a hose depends upon two things: the diameter of the hose, and the water pressure. Since both of these vary, there is no single answer to that question. However, a one inch diameter garden hose at an average household water pressure could be expected to yield about 200 gallons per hour, in my estimation. Your mileage may vary.

That's kinda gonna depend on how long the hose is. Without doing any figuresor math at all, we're pretty sure that a one-foot-long piece of 2-1/2" hose willhold more water than a 100-foot-long piece.In fact, when we do some figures, we can tell you that it'll hold one gallon of waterin every 47.1 inch length of hose.
