How does ice cool?
Water have a very high heat capacity and that mean water can contain a lot of heat which resulted in the cooling effect. Remember ice is water in solid form.

Y. Y Hsu has written: 'A criterion for the onset of quench for low flow reflood' -- subject(s): Cooling, Nuclear reactors, Emergency core cooling systems, Pressurized water reactors
Some examples of convection?
hot air rising cooling and falling :a hot air balloonboiled water or boiling waterhot air popper
Is this true that water contracts on cooling but it expands when cooled further from 4 degree C to 0 degree C?
Yes it contract and the expansion from 4 to 0 degrees is due to the crystallisation of water molecules.
How is a solids volume measured?
For finding volume you can use water displacement. Get a amount of water (make sure you know what number and how much) and drop your item in the water. The water should have risen. The difference of the Displaced water and the starting water should get you your volume.e.g. 16 mL of water, you drop a marble, the water is now 18 mL. So the volume of the marble is 2 mL.
Why the cooling water enters the condenser at the lower opening and leaves at the upper opening?
Cooling water enters the condenser at the lower opening to ensure efficient flow and circulation inside the condenser. As it absorbs heat from the hot vapor inside, it rises due to reduced density and leaves at the upper opening to maintain a continuous flow and maximize heat transfer. This upward flow helps in dissipating heat more effectively and prevents any potential blockages in the condenser.
Why should the water-inlet be at the lower end of the condenser?
The water inlet should be at the lower end of the condenser to ensure proper cooling efficiency. Placing it at the lower end allows for better circulation of the cooling water, which helps in maximizing heat transfer and improving the overall condensation process. This arrangement also helps in preventing air pockets from forming in the condenser, which could hinder its effectiveness.
What two places heat can be deposited in in a water-cooled condenser?
Heat can be deposited in the cooling water flowing through the condenser tubes and in the surrounding environment through air or another medium used for cooling.
In general where are salinity points located in the secondary side of a nuclear power plant?
Salinity points? In coastal plants using sea water cooling, a leak in the turbine condenser can allow sea water to enter the secondary water, as the secondary side is under vacuum in the condenser. Is this what you have in mind?
After heat is absorbed into a condenser medium in a water cooled condenser the heat can be deposited in one of two places what are they?
The heat absorbed by the condenser medium in a water-cooled condenser can be deposited either into the environment through the cooling water, which carries the heat away from the system via a cooling tower, or into another part of the system to be reused for heating purposes, like in a heat exchanger for a district heating system.
What TD is used to determine the condenser performance of a water cooled condenser?
The approach temperature difference (ATD) is used to determine the condenser performance of a water-cooled condenser. It is the temperature difference between the refrigerant condensing temperature and the cooling water inlet temperature. A lower ATD indicates better performance and efficiency of the condenser.
Why do you require a thermometer in a liebig condenser?
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.
What is reason for low vacuum in surface condenser?
Low vacuum in a surface condenser can be caused by air leakage into the system, inadequate cooling water flow, or a problem with the vacuum pump. It could also be due to high air or non-condensable gas content in the steam entering the condenser, which reduces the ability to create a vacuum. Regular maintenance and troubleshooting of these potential issues can help improve the vacuum in the condenser.
When water cooled condenser cycles off the regulating valve should?
When a system with a water-cooled condenser cycles off, the water regulating valve should
When water-cooled condenser cycles off the regulating valve should?
When a system with a water-cooled condenser cycles off, the water regulating valve should
In Liebig condenser what will happen if the water flow from the upper part to the lower part of the condenser?
If the water flow in a Liebig condenser is reversed from its intended direction, the cooling efficiency will decrease and the condensation of vapor inside the condenser will be less effective. This can result in lower overall condensation efficiency and potentially affect the distillation process taking place.
How can water enter the crankcase if not from the cooling system?
condentsation
