5.1 Water supply

Question 1

What is the primary disadvantage of a forward hose lay when flow rates increase?

a) Decreased friction loss in the supply line

b) Increased ease of connection to the hydrant

c) Friction loss becomes an issue

d) Improved efficiency in relay operations

Answer 1

C

Question 2

What is a benefit of a reverse hose lay in terms of friction loss?

a) Friction loss is not a concern in reverse lays

b) Friction loss is increased from the hydrant to the apparatus

c) Friction loss is decreased from the hydrant to the apparatus

d) Friction loss remains constant regardless of distance

Answer 2

C

Question 3

When is a split hose lay commonly used?

a) In residential areas with multiple hydrants

b) When approaching dead end streets

c) Only in industrial/commercial complexes

d) During static hose lays

Answer 3

B

Question 4

What is the characteristic of a static hose lay?

a) The apparatus secures its own water source

b) Hose is deployed from the water source to the incident

c) The apparatus drops supply hose at a certain point for another apparatus to connect

d) The apparatus arrives at the fire scene, and supply hose is dragged towards the hydrant

Answer 4

D

Question 5

Why might a static hose lay have disadvantages?

a) Friction loss is negligible

b) More firefighters are required as the distance from the hydrant increases

c) It is the most efficient method for long access roads

d) Flow rates do not impact static hose lays

Answer 5

B
