Given the values C = 1.43, Q = 5, and L = 2.5, what is the friction loss (FL)?

To find the friction loss (FL) using the given values, you would typically apply the formula that relates flow rate (Q), length of hose (L), and the coefficient of friction (C). The general formula for calculating friction loss in a fire hose is:

[ FL = C \times (Q^2) \times \left( \frac{L}{100} \right) ]

Where:

• FL is the friction loss in pounds per square inch (psi),

• C is the friction loss coefficient,

• Q is the flow rate in gallons per minute (GPM),

• L is the hose length in feet.

Plugging in the values you have:

1. C = 1.43

2. Q = 5

3. L = 2.5

First, you calculate ( Q^2 ):

[ Q^2 = 5^2 = 25 ]

Next, you calculate the friction loss for the given hose length:

[ FL = 1.43 \times 25 \times \left( \frac{2.5}{100} \right) ]

[ FL = 1.43 \times 25 \times 0.025 ]
