Fire Streams. 



Pressure required at nozzle and at pump, with quantity and pressure necessary to throw 

 good effective streams various distances through different size nozzles, using 100 feet of 

 ordinary 2^-inch rubber-lined hose and smooth nozzles.

The above pressures are based on the supposition that the hose is coupled direct to the 

 delivery of the pump ; if, however, the hose is coupled to a hydrant which is supplied direct 

 from the pump, then the corresponding fire pump pressure must be greater than the hydrant 

 pressure by an amount equal to friction loss, and difference of head between hydrant 

 and pump. 



The distances given are for effective fire streams adapted for fire purposes, and are not for 

 mere isolated drops.
