Flashcards in 7. Theoretical Pressure Calculations Deck (8)
Appliance pressure loss
It is assumed that there is a __ psi a loss for flows less than 350 GPM and a __ psi loss for each appliance in a hose assembly when flowing 350 GPM’s or greater.
A friction loss of __ psi for all master stream appliances regardless of flow will be used.
Elevation pressure loss in a multi story building
EP = 5 psi x (number of stories -1)
When considering pressure loss in an elevated waterway assume a loss of __ psi for the waterway and master stream appliance.
