What would be the estimated friction loss in a 600-foot length of hose flowing the same amount of water if 300 feet has a loss of 70 psi?

To determine the estimated friction loss in a 600-foot length of hose, you start by understanding the relationship of friction loss to the length of the hose. Friction loss in hoses is generally linear, meaning if you double the length of the hose, you would expect the friction loss to double as well.

In the scenario given, 300 feet of hose experiences a loss of 70 psi. To find out the friction loss for the entire 600-foot length, you can establish a ratio based on this known length. If 300 feet results in a friction loss of 70 psi, then for 600 feet, which is double the length, you would expect the friction loss to also double.

Calculating that gives:

70 psi (loss at 300 feet) x 2 = 140 psi (loss at 600 feet).

However, if we look at the original problem, it states that the 600 feet is flowing the same amount of water, which implies that the conditions of water flow may be influencing the friction loss in a more complex way. This could involve factors like flow rate and the internal conditions of the hoses. When using a fire flow calculation chart or formulas derived from empirical data, such contextual adjustments might show that the
