When supplying Truck 12 through 100' of 5" hose with a 2" tip, what is the friction loss if they need 170 psi at the inlet and hydrant pressure is 65 psi?

To determine the friction loss in this scenario, we first need to assess the pressures involved. The problem states that the required inlet pressure for Truck 12 is 170 psi, while the hydrant pressure (the pressure available at the source) is 65 psi.

The friction loss in the hose can be calculated by determining how much more pressure is needed to make up the difference between what is required at the truck and what is provided by the hydrant. This difference can be computed as follows:

1. Required Pressure at the Truck: 170 psi

2. Available Hydrant Pressure: 65 psi

To find the friction loss, we subtract the hydrant pressure from the desired inlet pressure:

Friction Loss = Required Inlet Pressure - Hydrant Pressure

Friction Loss = 170 psi - 65 psi

Friction Loss = 105 psi

However, it seems there might be a misunderstanding in interpreting the required data for calculation. Considering the total length of hose (100' of 5" hose) and using standard friction loss calculations for 5" hose, it typically has a coefficient that would need to be taken into account for pressure drops due to length and diameter of the hose.
