PIPE Elements 1 Flashcards
The output power available and delivered to the switchboard is:
Combined Power
Heat transfer due to density differential is:
Convection
It is a type of heat exchanger wherein the steam is not mixed or contaminated with cooling water in the condensing process.
Surface Condenser
A device that automatically allows accumulated liquid to pass from a higher pressure to a lower pressure region
Trap
It supply the required air combustion and to remove the product of combustion.
Draft System
The natural direction of heat flow is from a low temperature reservoir to a high temperature reservoir. The fact is incorporated in:
The law of refrigeration
An anergic system is one in which:
The system does no work nor is doing work on it
A heat exchanger that pre-heats feedwater using the heat of the flue gas is:
Economizer
What does the area under the curve in the pV-diagram represents?
Non-Flow Work
The engine cycle operating on two adiabatic and two isometric
processes is:
Otto
It is the lower temperature at which oil will flow under prescribes condition.
Pour Point
It is refined petroleum naphtha which by its composition is suitable for use as a carburetant in internal combustion engine.
Gasoline
It is a hydrocarbon fluid of high ignition quality
Octane
The volume of a gas is held constant while its temperature is lowered. The pressure of the gas exerts on the walls of its container decreases because:
The molecules have lower speeds and strikes the walls less often
The time rate of doing work
Power
A crack in the earth through which geothermal substance passes.
Fumarole
What are the largest fossil-fuel energy resources in the world?
Coal
It is defined as a petroleum distillate having a flash pot blow 22.8 oC
Kerosene
What is the condition of a fluid if its temperature is higher than the saturation temperature of the existing pressure?
Superheated
Is one whose temperature is below the saturation temperature corresponding to its pressure?
Sub-Cooled
The enthalpy of an ideal gas is a function of:
Temperature
The process that has no work transfer is;
Anergic
The theory of changing heat into mechanical work is;
Thermodynamics
A substance that follows the Pv = mRT relation is:
Perfect Gas
The force of gravity per unit volume is known as;
Specific Weight
