when the Liebig condenser was invented
Condenser pressure in an absorption chiller refers to the pressure within the condenser unit where the refrigerant vapor is condensed into a liquid. It is influenced by the temperature of the cooling medium (usually water or air) used to remove heat from the refrigerant. Maintaining appropriate condenser pressure is crucial for the efficient operation of the chiller, as it affects the overall performance and capacity of the cooling system. High condenser pressure can reduce efficiency and increase energy consumption, while low pressure can lead to inadequate refrigerant flow.
So that it can maintain a vacuum on the condenser; and the U-drains, which drain back to the condenser, don't get sucked dry by the ejector set. The length of each leg of U-drain is specifically designed to maintain a certain vacuum at each position. The U-drains drain the condensate from the inter and after condensers and the gland seal condenser back to the main condenser. Water under a perfect vacuum will stand in a column 34 feet high (10.33 meters), which means a vacuum of 30 inches of mercury (762 mm) would draw everything out of a column that is not at least that high. It's to maintain the water seal on the U-drains to prevent air induction into the condenser.

At first, it wasn't invented at all. It was harvested from the rubber tree in Brazil (Hevea Brasiliensis). Synthetic rubber came later (made from petroleum products).
The Liebig condenser was named after Justus Baron von Liebig . Since grammar school he was very interested in science and he used chemicals from his fathers dry saltery buseness to help him with his
Only the so-called Liebig condenser.
To keep the Liebig condenser cool so it can condense the vapour
Liebig condenser, Vigreaux column, Snyder column, West condenser, Allihn condenser, Graham condenser, Dimroth condenser, Friedrichs condenser. There are no shortage of these!
The Liebig condenser was named after the German chemist Justus von Liebig, who designed and popularized it in the 19th century. Liebig made significant contributions to the field of organic chemistry, and his condenser design greatly improved the efficiency of distillation processes by using a long, straight tube to increase surface area for better heat exchange.

A thermometer is required in a Liebig condenser to monitor and control the temperature of the cooling water flowing through the condenser. This is important to ensure optimal cooling efficiency and to prevent overheating, which could lead to loss of condensation and inefficient distillation.
More surface area.
Water typically cools to around room temperature (20-25°C) when passing through a Liebig condenser, which is a type of water-cooled condenser used in laboratory settings to cool hot vapors and condense them back into liquid form.
When designing a Liebig condenser for distillation, key considerations include the length and diameter of the condenser, the material it is made of, the cooling medium used, and the efficiency of heat transfer. These factors impact the condenser's ability to efficiently cool and condense vapors during the distillation process.
