What will be the friction loss when the layout is altered to include an appliance and the nozzle is taken to the sixth floor at a flow of 350 GPM?

To determine the friction loss when an appliance is included and water is being delivered to a nozzle on the sixth floor at a flow rate of 350 GPM, it's essential to consider both the flow rate and the elevation changes involved in the layout.

Friction loss is often calculated using formulas that take into account the diameter and length of the hose, as well as the flow rate. The addition of an appliance (such as a pump or any equipment that the water flows through) typically adds additional resistance, which increases the friction loss.

When water is taken to a higher elevation, in this case to the sixth floor, there is a significant increase in friction loss due to the height. For every 10 feet of elevation gain, you can estimate a static pressure loss of about 5 PSI. If the sixth floor represents approximately 60 feet, this would add roughly 30 PSI in friction loss just from elevation alone. When combined with the friction loss coming from the hose and appliance at the specified flow rate of 350 GPM, it brings the friction loss total to around 80 PSI, assuming reasonable losses from the hose and the appliance.

Thus, calculating all these factors indicates that the overall friction loss reaches 80 PSI when the nozzle is at the
