Student copy

Problem 1

Long courtyard stretch — the attack line works off a gated wye at the end of the lay.

The lines

  • Attack — 250 ft of 1¾ in hose, fog nozzle, 150 GPM at 100 psi, through an appliance (10 psi loss)

Required pump pressure (PDP) = __________ psi

Problem 2

Second crew stretches a backup line. One pump pressure has to serve both — gate the line that needs less.

The lines

  • Attack — 250 ft of 1¾ in hose, fog nozzle, 150 GPM at 100 psi
  • Backup — 200 ft of 2½ in hose, 1⅛ in smooth bore (50 psi tip)

Required pump pressure (PDP) = __________ psi

Problem 3

Heavy fire showing — the officer wants the two-and-a-half for reach and volume.

The lines

  • Big Line — 350 ft of 2½ in hose, fog nozzle, 250 GPM at 100 psi

Required pump pressure (PDP) = __________ psi

Problem 4

Automatic nozzle on the crosslay tonight. It makes a good-looking stream almost no matter what — so the pump panel, not your eyes, has to tell you the line is fed.

The lines

  • Attack — 150 ft of 1¾ in hose, automatic fog, 150 GPM at 100 psi

Required pump pressure (PDP) = __________ psi

Problem 5

The fire building sits up a grade from the engine — the line climbs the whole way.

The lines

  • Attack — 150 ft of 1¾ in hose, fog nozzle, 150 GPM at 100 psi, 40 ft above the pump

Required pump pressure (PDP) = __________ psi

Problem 6

Room-and-contents fire, single story. The officer calls for the crosslay to the front door.

The lines

  • Attack — 250 ft of 1¾ in hose, fog nozzle, 150 GPM at 100 psi

Required pump pressure (PDP) = __________ psi

Problem 7

Same crosslay, but which nozzle is on it tonight? Check the tip before you set the pump.

The lines

  • Attack — 150 ft of 1¾ in hose, fog nozzle, 150 GPM at 100 psi

Required pump pressure (PDP) = __________ psi

Problem 8

Heavy fire showing — the officer wants the two-and-a-half for reach and volume.

The lines

  • Big Line — 350 ft of 2½ in hose, fog nozzle, 250 GPM at 100 psi

Required pump pressure (PDP) = __________ psi
