Q

define jet assisted pumps

3rd 448

A

Utilize a small diameter in-line discharges inserted into the piping of a large tank when being supplied by fire pump water tender creating a Venturi affect - increasing water flow through the tank discharge

issues associated
must be quick to the fire pump
high velocity discharge my damage

Q

Which method is considered to be the simplest and quickest to ensure constant water supply for fire attack operation

A

Portable water tank operation

17
Q

Single portable tank operations are adequate for fire fighting that requires relatively low flow rates of less than how many GPM
3rd 462

A

300

18
Q

Low level strainers can allow for continuous draft to a shallow depth of how many inches
3rd 462

A

2”

19
Q

define jet siphon

3rd 463

A

Attached to a section of hard intake hose & a 1 3/4” hose line.

inlet of 1.5 inches receives water from 1 3/4” drawing water into hard intake hose and transferring it to adjacent tank

if flow requirements are greater than 500 gpm, parallel jet siphons should be considered

20
Q

Tender performance is based on what factors

3rd 464

A

Loading time
unloading time
drive train capability
tank size

21
Q

 Explain field test method to determine for calculations of a tender
3rd 465

A
Tender is parked in a position to dump into a portable tank
timer starts when valves opens
tender dumps tank
drives to fill site
returns back to the dump site
timer stops when tender is back

divide water dumped by time taken

.9 x tank size
——————-
trip time

22
Q

define insurance services office formula to evaluate water tender performance
3rd 465

A

calculate travel time
minutes .15= 15 + distance in miles

calculate handling time

23
Q

what percentage of a tenders total tank capacity is accounted for using the ISO equation and the field test method
3rd 467

A

90%
