When ur hot and ur working then it is hot working, if ur cold and ur working then it is cold working
What are the elements of a diesel power plant?
ESSENTIAL ELEMENTS OF DIESEL POWER PLANT Fuel Supply System It consists of storage tank, strainers, fuel transfer pump and all day fuel tank. The fuel oil is supplied at the plant site by rail or road. The oil is stored in the storage tank. From the storage tank, oil is pumped to smaller all day tank at daily or short intervals. From this tank, fuel oil is passed through strainers to remove suspended impurities. The clean oil is injected into the engine by fuel injection pump. Air Intake System This system supplies necessary air to the engine for fuel combustion. It consists of pipes for the supply of fresh air to the engine manifold. Filters are provided to remove dust particles from air which may act as abrasive in the engine cylinder. Exhaust System This system leads the engine exhaust gas outside the building and discharges it into atmosphere. A silencer is usually incorporated in the system to reduce the noise level. The exhaust system of a diesel engine performs three functions. First, the exhaust system routes the spent combustion gasses away from the engine, where they are diluted by the atmosphere. This keeps the area around the engine habitable. Second, the exhaust system confines and routes the gases to the turbocharger, if used. Third, the exhaust system allows mufflers to be used to reduce the engine noise. Cooling System The heat released by the burning of fuel in the engine cylinder is partially converted into work. The remainder part of the heat passes through the cylinder wall, piston, rings etc. and may cause damage to system. In order to keep the temperature of the engine parts within the safe operating limits, cooling is provided. The cooling system consists of a water source, pump and cooling towers. The pump circulates water through cylinder and head jacket. The water takes away heat form the engine and it becomes hot. The hot water is cooled by cooling towers and re circulated for cooling. Lubricating System The system minimises the wear of rubbing surfaces of the engine. It comprises of lubricating oil tank, pump, filter and oil cooler. The lubrication oil is drawn from the lubricating oil tank by the pump and is passed through filter to remove impurities .The clean lubrication oil is delivered to the points which require lubrication. The oil coolers incorporated in the system keep the temperature of the oil low. Engine Starting System This is an arrangement to rotate the engine initially, while starting, until firing starts and the unit runs with its own power. Small sets are started manually by handles but for larger units, compressed air is used for starting. In the latter case, air at high pressure is admitted to a few of the cylinders, making them to act as reciprocating air motors to turn over the engine shaft. The fuel is admitted to the remaining cylinders which makes the engine to start under its own power.
Weight difference in hot rolled and cold rolled?
The weight of the two is not much different, generally speaking, cold-rolled sheet is thinner than hot-rolled sheet, if you want to buy cold-rolled sheet or hot-rolled sheet, you can go to the official website of Changzheng, Changzheng's products are of high quality and are the choice of the public. If you want to buy cold rolled sheet or hot rolled sheet, you can go to the official website of Changzeng.
Are con-trails pollution?
no they are caused when hot exhaust gases hit the cold air,known as a vapor trail
Working principle of shell and tupe heat exchanger?
to cool hot fluit at certain temperature with the help of cold fluid
What happens when the cold and hot water pipes are reversed on the hot water tank?
You will get warm instead of hot water. There is a tube inside the tank on the cold side that goes to the bottom of the tank and the hot comes directly from the top. Reverse them and you are going to get the cold water that settles to the bottom of the tank. It will not hurt the tank or anything, it just makes for poor hot water.
What is a solar hot water system?
Domestic Hot Water Supply System The Solar Panel system is usually found on the roof, It uses the Sun's thermal radiation to warm up water for the house, the blackened layer absorbs the radiant energy and warms up the water flowing through the pipes. But the Hot water system uses cold water from the cold water supply tank and sinks it to the Boiler, where it is heated, and then the water which comes from the Solar panel system and water which comes from the boiler is collected in a hot water storage tank, to be used later. It is known that cold water sinks down and hot water rises up, and so if water in the hot water storage tank cools down it sinks down and then it is carried through pipes to the boiler to be reboiled.
Does water flow from hot to cold?
No, cold water is piped into the hot water tank and is heated by electricity or gas, it then flows out to the hot water taps.
Why do we call this system a self-pumping system?
A solar heater is called a self pumping system because cold water flows down the panels by itself when hot water rises into the tank.
Why is it so important to lag your hot water tank and your cold water pipes?
Lagging your hot water tank and cold water pipes helps to reduce heat loss and prevent freezing in colder temperatures. This can improve energy efficiency, reduce heating costs, and protect your plumbing system from damage.
Is Uranus hot or cold in the solar system?
cold
What to do when you lose hot water pressure and only have cold water pressure?
This depends on whether the hot water comes from a combination boiler or from a hot water tank with a header tank feeding it. For a combination boiler the fault would probably be at the boiler, possibly from scale in the heat exchanger. For the system that uses the header tank and a hot water cylinder it could be that the float valve in the header tank is stuck an there for it is not refilling the tank or debris has entered the tank and is blocking the outlet.
How does a hot-cold Water Dispenser work?
A hot-cold water dispenser typically has two separate tanks - one for hot water and one for cold water. The hot water tank is heated using a heating element, while the cold water tank is cooled using a cooling system, such as a compressor. When you dispense water, the machine draws from the appropriate tank and delivers the desired temperature of water through separate spouts or taps.
What side of the water does the pressure tank go hot or cold?
Install on cold water line.
Why Cold water is supplied to the bottom of hot water tank?
Cold water is supplied to the bottom of the hot water tank to prevent mixing of cold and hot water. This ensures that the hottest water is at the top of the tank where it can be drawn for use, while the cold water enters at the bottom to be heated by the heating element or burner. This also helps in creating a convection current within the tank for efficient heating.
What is the antifreeze level for Malibu 2001?
this should be marked on side of overflow tank, cold mark and hot mark,but check tank when cold and bring up to cold mark!!
In a direct system of a cold water supply what is the purpose of the cold feed pipe?
If you are referring to a regular building, the cold water feed pipe goes directly to all cold faucets, toilets and hot water tank. The purpose seems obvious.
