"Heating or cooling of processes, equipment, or enclosed environments are within the purview of thermal engineering.
One or more of the following disciplines may be involved in solving a particular thermal engineering problem:
Thermodynamics,
Fluid mechanics,
Heat transfer,
Mass transfer.
Thermal engineering may be practiced by mechanical engineers and chemical engineers.
One branch of knowledge used frequently in thermal engineering is that of thermofluids." [Thermal engineering. Wikipedia]

Interior Design. Plumbing — Design Elements

The plumbing system is a complex system of water supply pipes and drainpipes, sanitary equipment and drainage facilities, vent pipes and more. It supplies our homes, offices, hospitals, schools, business centers, and many other buildings with the main product for life - a water. For effective planning and montage the plumbing equipment, you need obligatory create and use different schematics of plumbing systems, the annotated plumbing diagrams, water lines and waste water plans. These diagrams are an obligatory part of any building project. They are used at all stages - construction, finishing works, interior design, and also during the exploitation of premises in cases of occurence some problems. Numerous libraries offered by the Plumbing and Piping Plans solution from Building Plans area of ConceptDraw Solution Park contain vector objects of plumbing components, sanitary equipment, bathroom fixtures, and many more for easy design the Plumbing and Piping plans, schematic diagrams and blueprints for hot and cold water supply systems, and waste water disposal systems.
This process flow diagram (PFD) example shows an amine treating system for the removal of gaseous hydrogen sulfide from gas streams. It is used in oil refineries and chemical plants.

"Amine gas treating, also known as gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from gases. It is a common unit process used in refineries, and is also used in petrochemical plants, natural gas processing plants and other industries.
Processes within oil refineries or chemical processing plants that remove hydrogen sulfide are referred to as "sweetening" processes because the odor of the processed products is improved by the absence of hydrogen sulfide. An alternative to the use of amines involves membrane technology. Membranes are attractive since no reagents are consumed.
Many different amines are used in gas treating:
Diethanolamine (DEA),
Monoethanolamine (MEA),
Methyldiethanolamine (MDEA),
Diisopropanolamine (DIPA),
Aminoethoxyethanol (Diglycolamine) (DGA).
The most commonly used amines in industrial plants are the alkanolamines DEA, MEA, and MDEA. These amines are also used in many oil refineries to remove sour gases from liquid hydrocarbons such as liquified petroleum gas (LPG)." [Amine gas treating. Wikipedia]

"An oil refinery or petroleum refinery is an industrial process plant where crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene and liquefied petroleum gas. Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units. In many ways, oil refineries use much of the technology of, and can be thought of, as types of chemical plants. The crude oil feedstock has typically been processed by an oil production plant. There is usually an oil depot (tank farm) at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products.
An oil refinery is considered an essential part of the midstream side of the petroleum industry." [en.wikipedia.org/ wiki/ Oil_ refinery]

Create Floor Plan

ConceptDraw DIAGRAM diagramming and vector drawing software extended with Floor Plans Solution from the Building Plans area of ConceptDraw Solution Park lets you the possibility to create Floor Plan of any complexity in minutes.
The vector stencils library "Design elements - Electron tubes" contains 36 element symbols of electron tubes.
Use it for drawing electrical schematics and electronic circuit diagrams.
"One classification of vacuum tubes is by the number of active electrodes, (neglecting the filament or heater). A device with two active elements is a diode, usually used for rectification. Devices with three elements are triodes used for amplification and switching. Additional electrodes create tetrodes, pentodes, and so forth, which have multiple additional functions made possible by the additional controllable electrodes.
Other classifications are:
(1) by frequency range (audio, radio, VHF, UHF, microwave),
(2) by power rating (small-signal, audio power, high-power radio transmitting),
(3) by design (e.g., sharp- versus remote-cutoff in some pentodes),
(4) by application (receiving tubes, transmitting tubes, amplifying or switching, rectification, mixing),
(5) special qualities (long life, very low microphonic and low noise audio amplification, and so on).
Multiple classifications may apply to a device; for example similar dual triodes can be used for audio preamplification and as flip-flops in computers, although linearity is important in the former case and long life in the latter.
Tubes have different functions, such as cathode ray tubes which create a beam of electrons for display purposes (such as the television picture tube) in addition to more specialized functions such as electron microscopy and electron beam lithography. X-ray tubes are also vacuum tubes. Phototubes and photomultipliers rely on electron flow through a vacuum, though in those cases electron emission from the cathode depends on energy from photons rather than thermionic emission."

"In architecture and building engineering, a floor plan otherwise known as a Scottish plan is a drawing to scale, showing a view from above, of the relationships between rooms, spaces and other physical features at one level of a structure.
The term may be used in general to describe any drawing showing the physical layout of objects.
A floor plan could show:
Interior walls and hallways;
Restrooms;
Windows and doors;
Appliances such as stoves, refrigerators, water heater etc.;
Interior features such as fireplaces, saunas and whirlpools;
The use of all rooms shall be indicated." [Floor plan. Wikipedia]

"In electronics, a vacuum tube, electron tube (in North America), tube, or thermionic valve or valve (in British English) is a device controlling electric current through a vacuum in a sealed container. The simplest vacuum tube, the diode, contains only two elements; current can only flow in one direction through the device between the two electrodes, as electrons emitted by the hot cathode travel through the tube and are collected by the anode. Addition of a third and additional electrodes allows the current flowing between cathode and anode to be controlled in various ways. The device can be used as an electronic amplifier, a rectifier, an electronically controlled switch, an oscillator, and for other purposes.
Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. Some electron tube devices rely on the properties of a discharge through an ionized gas." [Vacuum tube. Wikipedia]
"The EL34 is a thermionic valve or vacuum tube of the power pentode type. It has an international octal base (indicated by the '3' in the part number) and is found mainly in the final output stages of audio amplification circuits and was designed to be suitable as a series regulator by virtue of its high permissible voltage between heater and cathode and other parameters. The American RETMA tube designation number for this tube is 6CA7. Russian analog is 6P27S (Cyrillic: 6П27C )" [EL34. Wikipedia]

This plumbing and piping plan sample depicts the house hot and cold water supply and sanitation system.
"Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid. ...
Plumbing is a piping system with which most people are familiar, as it constitutes the form of fluid transportation that is used to provide potable water and fuels to their homes and businesses. Plumbing pipes also remove waste in the form of sewage, and allow venting of sewage gases to the outdoors. Fire sprinkler systems also use piping, and may transport nonpotable or potable water, or other fire-suppression fluids." [Piping. Wikipedia]
