    Temperature Drop of Compressed Air Tank

    Hello all, I'm busy calculating the time taken to fill a tank to a certain pressure. With the data from the compressor supplier, I've been successful in determining the time taken in IDEAL conditions. What I'm a little stumped on is the temperature of the tank while the compressor fills it...

    Compressed AirTank

    Compositepro, That's the scaffold I used. Good to know that it's in the right direction. Humidity ratio, aka specific humidity, allows me to quantify the vapor present after the whole cooling scenario. Once obtained, I can subtract from the initial vapor content, which then gives me the...

    Compressed AirTank

    tr1ntx, That's what I've gathered after piecing information. My need is to quantify the condensate collected, so that I can accurately size a moisture separator and a heat exchanger. I can share with you my computation, if desired. I've almost convinced myself that it's correct, but I can...

    Compressed AirTank

    racookpe1978, Firstly, thank you so much for your time. Are you sure the air will go in at over the boiling point of water? - The outlet temperature of the compressor is given at 250F (120C). So, yes the temperature in question is correct, but am I missing something here? And, that's what...

    Compressed AirTank

    fegenbush, I can't use the psychrometric chart, as the temperatures I'm dealing with are much higher. And, to be honest, I'm still unsure if that's the correct method for my problem. Perhaps if I provide some values and known information: I have already calculated the condensation occurring...

    Compressed AirTank

    Sorry, I didn't mean "dew point is LESS" I meant MORE.

    Compressed AirTank

    Racookpe1978, Thanks for your reply. I understand the thermodynamics within the compressor and am able to calculate the accumulation of condensate after each compressor cycle. What I need to know is when I've compressed the air into the tank. If I let enough time pass by, how much additional...

    Compressed AirTank

    I would appreciate if someone could correct me in this understanding. If a compressed air tank with 3000 psi and an internal saturation pressure much higher than ambient temperature is exposed to the ambient, the vapor pressure within the tank would decrease releasing heat and consequently...

    Relative Humidity and Dew Point after compression

    I really should have been clearer. So, after the intercooling within the five stage compressor, the exit temperature is at around 250F. I had misread the compressor specs. Considering ambient as intake and the exit at 3000psi. The saturation temperature at 3000 psi is 340F, so condensate will...

    Relative Humidity and Dew Point after compression

    crshears, I'm working with an oil-free breathing air compressor. It's a five stage oil-free compression. The information I do have is the outlet pressure and temperature, which is 3000 psi and 225degC. With this information I should be able to determine the relative humidity, dew point, and...

    Relative Humidity and Dew Point after compression

    Hello all, Would appreciate some guidance here. I have an air compressor compressing ambient air to 3000 psi into a 425cu-in tank. I have the volumetric flow rate at the exit. If I was looking for relative humidity, dew point, and moisture content/accumulation at the exit, how would I go...
