Answer 1

1,000 GPM

Question 2

Def. of Static pressure

Answer 2

When a pumper is connected to a hydrant and Not discharging water. The reading on the intake gauge.

Question 3

Def of Residual pressure

Answer 3

Once the pump begins to flow water. The reading on the Intake gauge.

Question 4

Def of Pressure drop

Answer 4

Difference between Static and Residual pressures

Question 5

First digit method

Answer 5

Static – Residual.
Take first number of Static, multiply by 1,2,3.
etc-

Question 6

Percent Drop method (4)

Answer 6

10% —-3x the flow
15% —-2x the flow
25% —-1x the flow
>25% water is still available.

Question 9

Transfer valve changeover

Less than 50% capacity

Answer 9

Net pressure— All

TV position– Pressure

Question 10

Transfer valve changeover

More than 50% capacity

Answer 10

Net pressure – LESS than 200 psi

TV position – Volume

Question 11

Transfer valve changeover

More than 50% capacity and over 200psi

Answer 11

Net pressure –MORE than 200psi
First try to pump in Volume if drafting.
Or in Pressure if working off a hydrant or in Relay.
