FAQ

I need to find out how to calculate the thermal efficiency of a heat transfer process using the flow rate, temperature change and input power.I know that the thermal efficiency is the power you put in divided by the power you get out but can't find out how to wokr this from the values I've got.

Work done BY the gas is given by the integral W = ∫ p dV from initial to final volume In the isochoric steps of the process no work is done, cause volume does no change

I am looking to find an approximate for temperatures you can acheive using solar flat plate or evacuated tube collectors for space heating? What temperature can water or air (an answer for both would be great!) reach in the system so that it could be put through a heat exchanger for space heating? Its for biomass drying therefore the higher the better. Thanks!

There is almost no limit. Using mirrors to simply focus sunlight yields temperature high enough to vaporize any material. A piece of flat iron (or a concrete driveway) left out in the sun will reach a temperature of 80 Celsius. You'll literally burn your feet walking on it.

the pressure is around 23 bar(g)

I don't believe there is an overall heat transfer coefficient for hydrogen. That term is normally used for a situation where there is heat transfer that is made up of multiple types of heat transfer and usually through a given surface such as a wall, heat exchanger surface or similar situation. The reference is one of several that gives conductivity information.

Heat exchanger is cracked. Still under warranty accept for install costs.

You aren't going to save anything by doing this yourself. I know...They've offered you the replacement part but wont cover the labour to switch it out! Problem is, you don't have the equipment to ensure the integrity of the installation of the replacement part. They will do some tests to make sure the heat exchanger is 'air-tight. This is one of those cases where it is not worth saving money! If you do this yourself and you have leaks, no matter how careful you are, you are placing yourself and your family at risk. Let a qualified installer do this for you. Yes, it will cost you some labour, but at least you can sleep nights knowing it has been installed properly and tested.

my teacher told to explain how a heat exchanger works in terms of 1) specific heat capacity2) specific latent heat3) temperature changes4) gas law and gas pressure

If you need more help, perhaps you could post a more detailed question?

what does a heat exchanger do on a chevy inboard on a boat?

Coolant from engine is circulated through a sealed system that uses ocean/lake/river water to cool it. This method allows antifreeze to be used in the engine vs outside water and doubles life of the engine.

my heat exchanger coils are freezing , why

usually when the lines ice over, it's a sign the unit is low on refrigerant.

I understand that it is essentially a loop in which a refrigerant travels around through the Earth's interior either cooling or heating and in the end expending that temperature into a home or building..as we know, technology is always progressing and ways of becoming more innovative and efficient are always just around the corner...so my question is...1.) What are some efforts or discoveries that increase the efficiency of the energy conversion in the process of Geothermal heating and cooling? So from what I interpret, are there any new ways to make the refrigerant travel faster...different types of refrigerant that are more efficient...a compressor that is able to get the job done more efficiently...etc...I had an idea though, I heard different types of refrigerants can be used such as air, water...etc???

we live in Northwest NJ. We put in geothermal in 1996. The preliminary value to place it in grew to become into high priced. We had placed an addition onto our domicile and grew to become into in prefer of a clean furnace, plus we would have cherished flow pug in finished domicile efficient air. the great value grew to become into putting interior the device because of value of the wells, 2 deep wells have been dug (there are no longer water properly, yet are drilled an identical way). We have been instructed we would have the return from our investment in 7 years, we figured we had it in a minimum of five years and nevertheless saving now. the completed each year value of our capability is below $3000. that includes, all heating, air con, cooking, inground pool, washing device dryer, all home equipment , electronics and lighting fixtures furniture. this could properly be a 2750sq feet. domicile. in this section a lot of our acquaintances spend $3000 or greater for domicile heating oil on my own! we adore the geothermal, the heating is humidified and filtered, and the air con is dehumidified and filtered. this is been a great capability value by way of the years.
