Q

What is the Flammability range, LEL, UEL?

A

-Flammability range: concentration range of a gas or vapour that will burn or explode if an ignition source is present. The limits of the flammable range are between the UEL and LEL.
-Ideal Mixture: (most efficient mixture, is the ratio of fuel to air that will burn with the maximum intensity and efficiency
-LEL: lowest concentration of a gas or a vapor in the atmosphere that will ignite in the presence of an ignition source.
-UEL: highest concentration of a gas or a vapor in the atmosphere that will ignite in the presence of an ignition source

36
What is cavitation, what causes it, and what are some indicators of it?
When in a vacuum, water boils at a lower temperature. This causes vapour bubbles to form and implode which can cause damage to the impeller and subsequentially, the pump. Causes: Lift too high, a restriction in suction hose, hydrant supply being overrun Indicators: sounds like small stones running through the pump, collector hose goes soft, compound gage will drop, decrease in delivery flow, engine revolutions increase
37
Why should the onboard water tank be filled immediately?
So that there is always a reserve supply of water, should a hydrant supply or collector hose fail.
38
What are the gauges on a pump panel and what do they indicate?
-Compound gauge: indicates the pressure of water entering the pump from closed supplies in kPa. When the zero is crossed and the needle runs into the red it means supply is being over-run (cavitation). When used for draughting it indicates the height of lift from open supplies in kPa. Each -kPa calibration equals 1m lift -Main pressure gauge: shows the delivery pressure in kPa that the main pump is generating. -High pressure gauge: shows the delivery pressure in kPa that the HP pump is generating. -Flow gauge: Amount of flow in L/min through the delivery valves.
39
What is the maximum practical suction lift in the ACT?
7.5
40
What are some supplementary cooling techniques?

41
What is the main function of the pressure relief valve?
To reduce the impact of any sudden closing of branches which can send shock to the other branch crew
42
What is the maximum pressure that the relief valve will bleed off?
200kpa
43
