1. Calculate the total friction loss by using the following details. Be sure to show all of your work. In the table below, clearly indicate your final answer along with the appropriate units of measure (i.e., The total friction loss is XX psi for XXX feet of X-inch hose). Round your answer to the nearest whole number.

Hose diameter

1.75-inch

Volume (of water) 

150 gpm

Hose length 

300 feet 

Friction loss = 

 

2. Determine the pump discharge pressure for a scenario containing the following details. You are using a handheld smooth-bore nozzle for this scenario. Be sure to show all of your work. In the table below, clearly indicate the total friction loss, pump discharge pressure, along with the appropriate units of measure (i.e., The total friction loss is XX psi for XXX feet of X-inch hose plus any applicable appliance loss or elevation gain/loss). Round your answer to the nearest whole number.
