Sentences with phrase «water as coolant»

We do not run water as coolant in road vehicles due to the corrosion problems it can cause to the internal water passageways of the engine, and also due to issues with expansion, if the water were to freeze it can crack the engine block itself.

There are some 50 modular designs being developed globally, and while many are traditional light water reactors, which use water to cool the reactor core, others gain efficiency by using coolants such as gas, which allow reactors to reach higher temperatures.

PHWRs are similar to PWRs, but use raw uranium rather than enriched uranium oxide as fuel, and deploy heavy water — in which hydrogen is replaced by deuterium — as both moderator and coolant.

Enriched uranium oxide is formed into rods and water is used both as a coolant, flowing through the reactor core to transfer heat away, and as a moderator, slowing down neutrons released by fission so that they promote further nuclear reactions.

The fuel is enriched uranium oxide, and water is used both as a coolant and as a moderator.

Being the same weight as neutrons, conservation of momentum and energy tell us that a neutron striking a hydrogen atom can slow down all the way from super fast to zero in one collision (imagine a billiard ball striking a stationary one), so water coolant is very good at slowing fast neutrons down to thermal energies.

Instead of water, liquid sodium is typically used as a coolant because the sodium atoms are so much larger and heavier than neutrons that when they collide the neutrons simply ricochet off the sodium atom - much a like a small bullet ricocheting off a thick plate metal.

This is why normal water is used as a coolant in most thermal neutron reactors.

For this reason, water is unsuitable as a coolant because it tends to turn fast neutrons into thermal neutrons.

Unlike the current generation of light - water nuclear reactors, PRISM uses metallic fuel, such as an alloy of zirconium, uranium, and plutonium, and PRISM's fuel rods sit in a bath of a liquid metal — sodium — at atmospheric pressure, which ensures that the transfer of heat from the metal fuel to the liquid sodium coolant is extremely efficient.

When water used as a coolant is returned to the natural environment at a higher temperature, the change in temperature impacts organisms by (a) decreasing oxygen supply, and (b) affecting ecosystem composition.

It would not be the water pump as in most every engine I've seen there isn't any oil passages going to it, just coolant.

The coolant is circulated by a pump known as the «water pump».

I have just recently changed the radiator in my vehicle upon changing noticed smoke coming out of the coolant resivour as I added water into the resivour it was getting oil into the coolant system.

In case I am not able to locate these two bolts, Is that a strictly necessary step since hopefully as water runs through the system the engine block coolant should be pushed out by the water eventually correct?

As the coolant is moved around the system by the water pump, it passes through two main components:

I believe most modern Volkswagen based engines since as far back as the 1992 VR6 engine have a secondary water pump which circulates coolant after the engine is shut off.

You're changing the water pump, so that's a good opportunity to do a coolant flush as well.

Considering the age of the car, it could be as simple as a cracked or loose coolant hose (fairly cheap), or a failing water pump (not very cheap).

Because water has good properties as a coolant, antifreeze is used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters.

After a year I had to check again condition of coolant and it did not have any rust deposits and was «just as liquid» as a new 50:50 coolant - water mixture.

EDIT: As for the low coolant, if possible, you should inspect the coolant hoses and water pump for leaks, or have a mechanic do the same.

Typically coolants are not as efficient as plain water at taking heat away from the hot parts of the engine and loosing that heat in the radiator.

You do want to check the ratio of coolant and water as straight coolant (or too much compared to water) will not cool as well.

Map - controlled electrically operated continued coolant circulation pump - V51 as back - up for mechanical water pump and for continued coolant circulation

Best guess based on your explanation: First the water pump quit / died, then engine overheated as a result and it remained running overly - hot for sometime thereafter, which (likely) led to head gasket failure, which resulted with coolant in the oil and the performance symptoms.

As per the picture below, coolant is oozing out of the front of the engine, above the water pump (replaced last fall) and below the thermostat.

Most modern automotive engines are both water and air - cooled, as the water / liquid - coolant is carried to air - cooled fins and / or fans, whereas larger engines may be singularly water - cooled as they are stationary and have a constant supply of water through water - mains or fresh - water, while most power tool engines and other small engines are air - cooled.

I would check the coolant reservoir to verify its full, if its low look for leaks around the water pump, radiator, hoses and around the intake as coolant runs through certain parts of it.

Coolant — as its name suggests — offers the additional cooling advantage of raising the boiling point of water.

Critical parts like fuel filter, engine coolant, brake fluid and water pump drive belt have different timings as listed below:

Coolant leaks may come from a variety of places such as any of the hoses that go to or from the radiator to the motor, the thermostat housing, the water pump or potentially the radiator itself.

Hello - if the coolant temperature is truly getting as hot as you describe, and the thermostat and water pump are transferring that heat to the radiator, the coolant fan temperature switch (https://www.yourmechanic.com/services/thermo-coolant-fan-switch-replacement), or it's relay and wiring, are malfunctioning...

There is water cooling as electrical systems run hot too, and on the Soul EV there's a heat pump system that recovers waste heat from the coolant to the cabin climate control system.
