Minimum
temperature at which a fluid
will support instantaneous combustion
(a flash) but before it will
burn continuously (fire point).
Flash point is an important
indicator of the fire and explosion
hazards associated with a petroleum
product.
Friction
Resistance
to motion of one object over
another. Friction depends on
the smoothness of the contacting
surfaces, as well as the force
with which they are pressed
together, motion and is expressed
as share stress unlike solid
friction, fluid friction.
Fuel
Ethanol
Ethanol
(ethyl alcohol, C2H5OH) with
impurities including water but
excluding denaturants.
...........\\\///............
Gaseous
Fuels
Liquified
or compressed hydrocarbon gases
(propane butane of natural gas)
which are finding increasing
use in motor vehicles as replacements
for gasoline and diesel fuel.
Gasoline
A
volatile mixture of liquid hydrocarbons,
containing small amounts of
additive and suiTable for use
as a fuel in spark ignition
internal combustion engines.
Gasoline
Ethanol Blend
A
spark-ignition automotive engine
fuel containing denatured fuel
ethanol in a base gasoline.
It may be leaded or unleaded.
Gravity
In
petroleum products, the mass/volume
relationship expressed as
:
Mass/unit

Gross
Additive Treating Cost (GATC)
The
cost of additive in one volume
unit of finished product not
including base fluid credit
or shipping costs.
Gross
Delivered Treating Cost (GDTC)
The
cost of additive in one volume
unit of finished product including
shipping cost, but not base
fluid credit.
