Q:
# How much water comes out of a garden hose?

A:
### Quick Answer

The rate of flow of water from a garden hose depends on the diameter of the hose, length of the hose and pounds per square inch (psi) of pressure when the water is on. Additionally, hose heads and sprayers that adjust the amount of output can also be purchased.

For example, a 1/2 inch hose that is 100 feet long and has a pressure of 40 psi has a water flow of about 6 gallons per minute. Some hose manufacturers create hoses out of special materials or with special nozzles that increase the flow rate of water and can achieve a flow rate of as many as 4 1/2 gallons of water per minute.

Q:
## How do you calculate friction loss in a fire hose?

A:

Full Answer >**Friction loss in a fire hose is calculated by multiplying the friction loss coefficient by the flow rate divided by 100 to the power of two and multiplying that by the hose length divided by 100.**Distance, diameter and GPM must be considered when calculating the friction loss.Filed Under: -
Q:
## What is the definition of differential pressure?

A:

Full Answer >**The term "differential pressure" refers to fluid force per unit, measured in pounds per square inch (PSI) or a similar unit subtracted from a higher level of force per unit.**This calculation could be taken for pressures inside and outside a pipe or simply in different places along a flow path. This calculation has applications in the drilling industry.Filed Under: -
Q:
## What are some steel pipe pressure limitations?

A:Standard pressure limitations for a schedule 40, 1-inch stainless-steel pipe are 3048 pounds per square inch at 100 degrees Fahrenheit, 2019 PSI at 500 degrees and 1810 PSI at 750 degrees. Pipes have a maximum pressure curve, as the temperature of the air affects their pressure limitations.
