What percent water are jelleyfish?
How much percent water are in a jellyfish? Answer The body of an adult jellyfish is made up of 94 to 98 percent water. Scroll down to related links and look for "Jellyfish - Wikipedia".
What percent of earth is land?
about 25% is land. 75% is water.
What percent of pear is water?
A pear is an infinitesimal percent of water. There's so much water out there, and the pear contains so little of it, that it's not really worth knowing.
What percent of drowned victims are not wearing a life jacket?
Approximately 90% of drowning victims are not wearing a life jacket. Wearing a life jacket is important for water safety, especially for boating and activities in open water.
Are all living things made up of about 70 percent water?
No, not all living things are made up of about 70 percent water. Organisms can have varying percentages of water in their bodies depending on their species and environment. For example, some plants may have a higher water content, while certain animals that live in dry environments may have lower water content.
Which is better fire tube boiler or water tube boiler?
The words are literal , a water tube boiler is water inside the tubes with hot gases surrounding them and a fire tube boiler are got gases within the tubes with water surrounding them.
How does the fire tube boiler operate?
In a fire tube boiler, the water surrounds a set of tubes through which the fire and the products of combustion travel (as opposed to a water tube boiler, in which the water travels through the tubes, and the fire surrounds the tubes).The HVAC Veteran
Difference between water tube boiler and fire tube boiler?
The answer is in the name. Boilers are made with a "tube - in - shell" construction, and the name implies what is in the tube. In a water tube boiler, the water circulates through the tubes, and the burner is usually under them. Most of the time, the "shell" of this style of boiler would not be watertight. A fire tube boiler has a watertight outer jacket with tubes through the center of it. The flame is shot through the tubes.
What will be the effect of lower water level in boiler?
Effect of low water level in the boiler is rapid increase the temperature of the metal tubes, causing a collapse or rupture.
What will the effect of the lower water level in the boiler?
Effect of low water level in the boiler is rapid increase the temperature of the metal tubes, causing a collapse or rupture.
Why water demineralized used in a boiler?
Demineralized water is used in boilers to prevent mineral buildup that can lead to scale formation. This helps maintain efficient heat transfer and prevent corrosion in the boiler system. Using demineralized water can also increase the lifespan of the boiler components.
In which type of boiler you can find water walls?
A waterwall in a boiler is any furnace wall that is comprised of refractory and tubes in a water-tube boiler. The tubes are evenly spaced and generally connect to headers which in turn are connected back to the main generating bank of the boiler. They serve a two fold purpose here in that they capture heat that would otherwise escape to the atmosphere and help heat the water in the boiler. And they also help keep the refractory cool (relatively speaking) This prevents spalling of the refractory.
What are some applications for a water tube boiler?
Water tube boilers are used in marine and stationary applications. A water tube boiler heats by water flowing through tubes and being heated by fire externally.
What is the thermodynamic process carried out in steam boiler?
The water tube boiler forces water through tubes and heats these tubes from the outside. This is done in a combustion boiler, or in the steam generator of a pressurized water nuclear reactor. It could even be done in a thermal vent in a geologically active area. The heat penetrates the tubes and increases the thermal energy of the water in the tubes and turns it to steam. The steam is sent to do work, as in a turbine. The steam loses thermal energy as it passes through the turbine, and it eventually exits the turbine as low energy steam. It is then dumped into a condenser. Here the "last little bit" of the steam's energy is removed by the cooling water passing through tubes in the condenser, and the steam is turned back into water. The water is them pumped back through the water tubes in the boiler or steam generator to repeat the cycle. The
What will happen when boiler steam drum level goes down?
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
What is water wall in boiler?
A waterwall in a boiler is any furnace wall that is comprised of refractory and tubes in a water-tube boiler.

Why water tubes are inclined in Babcock Wilcox boiler?
They are inclined so that hot flue gases come in contact with hottest water.
