A

The Friction Loss Pump Chart: High Rise Standpipe Operations.

135
Q

If the high rise is equipped with Pressure Reducing Valves (PRVs) what must the engine pump?

A

It must pump as if the fire were on the roof of the building.

136
Q

What must you do if the FDC is damaged or inoperable?

A

Apparatus operators and suppling the system.

145
Q

Q

What can help a single engine overcome required building pump pressures?

A

A series pump operation.

151
Q

What is a series pump operation?

A

Series pumping is actually a short relay pump operation in which the engine receiving water from the hydrant then pumps into the intake of the second engine. This allows the second engine to boost the psi even higher.
