It is important to maintain a vacuum in a condenser if you want it to work well.
A kenotometer is an instrument used in steam turbine condensers to measure the vacuum in the steam space of the condenser. The vacuum achieved by the condenser has significant influence on the efficiency of the steam turbine.
Many factors affect welding depth and penetration, including voltage, material being welded, current, distance from electron gun, vacuum, cleanliness, filament current, and focus.
A magneto is an electric generator that is powered by magnets. Some factors that will affect its performance include their power source as well as the reliability.
Unlike a static condenser (capacitor bank), the value of reactive power from a synchronous condenser can be continuously adjusted. A synchronous condenser also has other advantages over static condensers such as: - not being affecting by harmonics (some harmonics can even be absorbed by a synch condenser) - producing no switching transients
tube fouling, clogged tube, air leak affects heat transfer.
An atmospheric condenser operates naturally at atmospheric pressure (1.013bar). A vacuum condenser operates at pressures below atmospheric and will use some sort of pump to provide a vacuum.
For increasing steam turbine efficiency. if vacuum is not maintained then, uncondensable gases and air in condenser will increase the condenser pressure.

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

Reasons for low vacuum: 1. Low gland sealing pressure 2. Condenser tubes choked 3. Condenser cooling water temperature high 4. Leakage in condenser tubes 5. Less cooling water flow

If you are talking about a condenser attached to a steam turbine, then a vacuum is important because it extends the usefulness of the steam in the turbine. As you probably know, steam begins to condense back into water at 212 deg at atmospheric pressure. However, in a vacuum condition, the boiling and condensing temperature is lower. Because the condenser is under a vacuum, steam exits the turbine and enters the condenser around 130 deg. This results in more power (mega watts).
If the vacuum in the surface condenser it very high, it results in higher practical thermal efficiency. It is important for you to keep the temperature to 100 Celsius or lower for it to work properly.
The AC condenser would effect the performance of the AC system in the car.
A vacuum pump is used to expel air and non-condensible gases from the condenser in order to allow it to continue accepting steam (the collapse of which produces the vacuum in a condenser). If the vacuum pump fails, it will take from seconds to a few minutes before enough non-condensible gases build up in the condenser to stop the flow of steam. The non-condensible gases come from the boiler feedwater supply, despite the fact that boiler water is treated to prevent this. The minute amount of air in the water is carried with the steam into the turbine then the condenser where it will concentrate unless removed by the vacuum pump.
