Explanation: In a low level parallel flow type jet condenser, the steam comes in direct contact with the cooling water. The proper mixing is ensured using a baffle plate. The condensate is collected at the bottom of the condenser. The condensate extraction pump is hence located at the bottom of the condenser.

There are three main types: air-cooled, evaporative, and water-cooled condensers.

In high level jet condensers, the condensate falls to the hot well by the barometric leg provided in the condenser. Condensers are classified as follows: In jet condensers which is to be condensed. In surface conden the steam which is to be condens In parallel flow the same direction.

The main sources of air leakage in the condenser are: (i) Leakage of air from atmosphere at the joints of the parts which are at pressure less than atmospheric pressure. (ii) Air is coming from the boiler along with steam. This air enters in the dissolved form in the feed water.

Explanation: Air leakage in the condenser reduces the thermal efficiency of the steam power plant. It increases the amount of cooling water required and also increases the corrosive action in the condenser. The heat transfer rate in the condenser is reduced.

Advantages & Disadvantages of Surface Condensers: 3/8/2016Footer Text 19 Advantages:  High vacuum efficiency.  Pure condensate.  Low quality cooling water can be used.  It allows the expansion of steam through a higher pressure ratio.

It is also said to be “cold” because if you leave a relatively warm object in vacuum, it will rapidly radiate away the heat. Vacuum is cold in the sense that it has a very steep temperature gradient. It is not cold in the sense that it has particles that have low kinetic energy.

IN SPACE, no one can hear you scream. Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.

Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.
