OK so the leak is the one on the tool. I couldn't get this from your first post. Not much of a design improvement, but my first solution would be: throw the tool, buy a new one and forget the problem! I suppose you know the ball valve must be turned exactly 90° to shut completely. If you...

A compression process is a transformation that reduces the volume of the fluid you are compressing. You can reduce the volume following the rule that P V^(-3.1416) remains constant. You can also reduce the volume of the same fluid following the rule P V^(+3.1416) remains constant. For that to...

Hmmmm… I suspect we are not talking about the same type of valve or you want to give the core remover tool a use it is not designed for. Bigger or smaller, the ones I work with have the schraeder valve independent from the stem assembly like here...

For a general equation for heat capacity, and not just for ideal gases look here: http://www.manchesteruniversitypress.co.uk/uploads/docs/290227.pdf n can take any real value. The integrals you usually see are not valid for n=1 only because this is a special case, not that the integral would...

If you can install individual condensers closer to each compressor this obviously saves energy over one distant condenser. If the volume ratio of the compressor's is such that as separate systems they would work with the same condensing pressure, there is no difference whether you use one or...

Manufacturer's data includes latent load. If cooling below dew point is required then latent load must be taken into account. Desecants are economical only in over saturated or high RH flows. If the desired RH was reached (and final absolute moisture content) with the desecant only, there is...

Can't say it is a common problem. It happens in poorly assembled or very old/used ball valves. The ball valve should have a cup to cover the stem and prevent leaks to the atmosphere. The core remover tool can't fix this problem. It is only designed to change schraeder's valve core. You should...

I think it should read: "... vent hole and a check valve ..."

Is possible to have a n<k compression process? Of course! In particular n=1<k is one of such processes. Having 1<n<k only means that your process is neither isothermal nor isentropic, allow temperature variation and energy flow through the borders and you have it! n<1 are all possible even...

First look for the definition of "static pressure", it should be close to 0 for working and non working tunnels, unless the tunnel is miles high.

Depends on PHE design (size, corrugation, plates, ...) Get manufacturer´s calculation programs like here: www.kelpie.se

First check the pressure reached at startup and the pressure switch setting. If the high pressure is not normal but the switch is ok you may have a faulty/dirty expansion device. Only if this fails I agree with the other suggestions.

MintJulep: People disagree on this matter only because they make different assumptions and the problem is they are not even aware they made them! Thermodynamics teach that if there is thermodynamic equilibrium you MUST have a saturation conditions. But a liquid receiver is seldom at a state of...

I have little experience with Bitzer compressors but in order of priority you could have one or more of the following: 1) Liquid refrigerant flood back would be the first thing to check by measuring superheat at compressor suction. Discard this choice if it measures 10F or higher (lower values...

Hi, Look under Defining Terms at the bottom of the page here: http://books.google.com/books?id=cvZtAtz01XAC&pg=PT435&lpg=PT435&dq=%22specific+deflection%22&source=web&ots=7LZn3_6z62&sig=kpTDDwVC_C8ubhgXFP1NBsuuP0M&hl=en&sa=X&oi=book_result&resnum=5&ct=result#PPT435,M1 It is a custom to...

Hi, My humble guess is the shower's dew point is it's ambient temperature because it should be over saturated with water. This temperature should (normally) be higher than that of the walls of the duct because the shower gets heat from hot water. So unless you heat up the air in the duct I...
