Condenser Backpressure is the difference between the Atmospheric Pressure and the Vacuum Reading of the Condenser, that is:
Backpressure = Atm. Pressure - Condenser Vacuum Pressure Reading
Usually, the condenser vacuum pressure is read by a manometer installed at the condenser. The atmospheric pressure is read using a barometer

What does the venous system do?
The venous system is responsible for returning deoxygenated blood from the tissues back to the heart. It transports this blood through a network of veins, which have valves to prevent the backflow of blood. The venous system also plays a role in regulating blood volume and pressure in the body.
What causes excess fluid in the interstitial compartment?
There is hydrostatic pressure within the capillary pushing the fluid out because fluid will always flow from high pressure to low pressure. At the same time there is something called blood colloid osmotic pressure which is the formed elements and larger plasma components such as proteins drawing fluid back into the capillary lumen by osmosis. The end result is that nearly just as much fluid that is filtered out at one end is reabsorbed by the time it reaches the other end. This is known as Starlings Law of the capillaries.What little excess isn't reabsorbed by the capillary will be picked up and returned to the cardiovascular system through the lymphatic system.
How can the gases can be liquefied?
Liquefaction by cooling down (lower temperature) and compression (higher pressure)
How does a back boiler work scientifically?
A boiler works by heating water in an enclosed space. The expansion of water molecules as it transforms from a liquid state into a gaseous one causes the boiler to generate a vast amount of pressure. This is generally the science behind a back boiler.
Is a high pressure sunny and bright?
Pressure is force divided by area. An increase in pressure is due to atmospheric gas (particles) being forced downwards. Due to thermodynamics this increase in air pressure leads to heating ( pv=nRT ) thus preventing condensation (no clouds = sun). Low pressure is due to air moving upwards leading to expansion and therefore cooling of the gas promoting condensation (clouds = rain) Here is how low pressure relates to bad weather... given the right conditions. High pressure generally relates to "nicer" weather, while low pressure often relates to bad weather. This is because these pressure systems have their own general characteristics. One characteristic I like to use while observing weather conditions such as pressure and making forcasts is the rotational direction of these pressure systems. For example, low pressure systems rotate counterclockwise in the northern hemisphere, while high pressure systems rotate clockwise. With low pressure systems, counterclockwise rotation causes converging winds. This means that the winds are coming together. Where are they coming from? Pressure moves from high pressure systems to low pressure systems. Therefore, moving air causes wind. When this air converges (as in a low pressure, counterclockwise system), due to its rotation, the air gets forced downward. In general, when this air is forced to the ground and has nowhere to go, it pushes out and back up around the center of the low pressure system. This upward movement of air causes instability in the atmosphere, which equals clouds, especially when the air being drawn in (converging air) has a different temperature than the air that it is replacing. Warm air below cooler air equals instability and rising thermals (rising hot air). There are many variables left out in this simple explaination, but in general it quickly answers the question. High pressure systems diverge air and therefore are the opposite. One has to remember, however, that these systems can interact in very complicated and unpredictable ways. -RJS
What is a back flush on the cooling system?
Back flushing on a cooling system is when you get all of the trapped air out of your cars cooling system. This will make your vehicle run better after you do it.
What is presurised cooing system?
All auto cooling systems are pressurized. The radiator cap holds the pressure in the system at about 15Lbs. The reason for it is it causes the boiling point of water to be at a higher temperature so the water doesn't boil away as easily. The big white tank beside the radiator allows boiled water STEAM to stay in the cooling system and condense back to water and return back into the radiator as it cools. Champ390
How does a radiator overflow tank work?
When the fluid in the cooling system heats up, it expands, causing the pressure to build up. The cap is the only place where this pressure can escape, so the setting of the spring on the cap determines the maximum pressure in the cooling system. When the pressure reaches 15 psi, the pressure pushes the valve open, allowing coolant to escape from the cooling system. This coolant flows through the overflow tube into the bottom of the overflow tank. This arrangement keeps air out of the system. When the radiator cools back down, a vacuum is created in the cooling system that pulls open another spring loaded valve, sucking water back in from the bottom of the overflow tank to replace the water that was expelled.
2000 Chrysler Neon AC refrigerant full but no cooling?
the AC needs to be recovered and placed back into the system. there is not enough pressure in it to cool
What happening if you are overcharging an air conditioning system with refrigerant?
For starters, you'll get insufficient cooling from your system. Refrigerant changes states from liquid to vapor and back again in order to achieve cooling, and the system pressure is balanced to facilitate this - excessive refrigerant makes it much more difficult to do this. Additionally, your system will generate excessively high pressure, which will ultimately damage or destroy system components.
On a 1998 Chevrolet Malibu How do you flush the cooling system?
It is best to have it done professionally as they clean the cooling system as well as back flush it.
How to get oil out your cooling system?
It will take a few flushings to get all of that solution back out of the to be oil in the cooling system so it probably doesn't have a lot of oil removal capacity.
Why would a Bluebird cooling system be overheating and bubbling back into the over flow bottle after having the radiator replaced?
Air in the system. Bleed the cooling system and remove any trapped air pockets.
What is causing the coolant to blow back into the overflow on a 2003 Toyota Highlander 4 cylinder.?
The description of the symptom could indicatev a head gasket leak allowing the pressure of the combustion chamber to intrude into the cooling system and forcing the coolant out.
How does the coolant reservoir work?
when the engine is running and coolant will become hot to its operating temperature,the cooling system is under pressure,coolant will overflow and goes to coolant reservoir.when the engine goes cold coolant will go back to the rediator.
Cooling the air to a temperature below the dew point causes the water vapor to begin to change back into a liquid is what process?
Condensation
What is the purpose of having a back pressure valve in marine refrigeration system?
when two refrigerated spaces are severed by only one compresser & condenser but need to be maintained at different temps. a back pressure regulator comes into play. The back pressure regulator will be installed on the outlet of the refrigeration system to maintain a minimum back pressure in the evap coils. Since pressure is directly related to temp. then the temp. desired can be maintained by the pressure you set.
