etudiant, Thank you for the response. I'm essentially trying to construct a beverage launcher. I have seen others out-there, but I'm trying to re-invent it a little with my own spin, and keeping it simple. Earlier when I was thinking of trebuchets or catapults, I had my horse-blinders on and...

Hello folks, I have very little robotic experience, so would like to start my knowledge accumulation here at PhysicsForums. I am trying to design and build a launching mechanism to launch a 400 gram projectile. I was hoping to get a bit of guidance in what devices I should be looking into...

Have a new task, would appreciate some pointers. Conducting a heat transfer analysis on a tank with water coming in and out that's to serve as a hot side for a displacing stirling engine. If the inlet q dot into the tank is 1000W. Observing there will be losses due to conduction and...

I like the copper pipe idea. Is it safe to assume that the condensate formed due to temperature drop through the copper pipe would be negligible since the compressor has an integrated dryer? If not, how to keep the moisture out? Another desiccant type moisture collector? You're right about the...

And, I forgot to say that I do indeed have a pressure regulator capped at 300 psi.

Well Baluncore, I apologize for not providing more info. Just ask, no worries. I appreciate your and others' time. So, to be clear: I have a compressor which operates at 1.30 CFM at 0 psi, and decreases with a polynomial relationship to 0.80 CFM at 300 psi (This relation is hard to put in an...

I doubt you can ignore the effects of temperature when you're looking at CFM's of 1.2. The density of air will be effected as result, and in turn effecting the pressure. When one has the psi to cfm chart, I don't know why use the worst case as the fill time, since that won't be accurate or...

Actually, I don't think choking will occur. Someone please confirm this. As I have the flow rate vs pressure information from the compressor, this just tells me that when the air tank pressure is at ambient, the flow rate is just higher, and when the pressure increases in the tank, the flow...

Hello friends, I'm trying to calculate the fill time to compress an air tank. I currently have the compressor's flow rate[CFM] at various pressures[PSI]. I honestly thought it was a trivial endeavor until I started gathering all the critical elements. So, there's obviously flow rate...

Sakthi, Thanks for getting back. The formula used is conducted by W. Wagner and A. Prub called "The IAPWS Formulation 1995 for the Thermodynamic Properties of Ordinary Water Substance for General and Scientific Use" in the Journal of Physical and Chemical Reference Data. I ran a few data...

Correct me if I'm wrong. Pressure is an addition of Partial Pressure of Dry Air Pressure and Vapor Pressure. If a tank is exposed to ambient air, which is much cooler than the saturation pressure within the tank, then the release of heat within will decrease the partial pressure of vapor which...

If I allow a tank that's pressurized(3000 psi) and initial temp (121) to cool to room temperature (25 C), will that increase the rate of condensation or is there a fixed amount of condensation that occurs while at that pressure? Having a tough time understanding that phenomenon. If no change in...

Sakthi, That was very well put. I understand the system a little better. To add though, I had mistyped the temp, it's in fact 225F and not 225C. So, condensate will occur after the compression. I'm trying to determine the actual condensate quantity of accumulation or at least the rate. Can I...

Sakthi1267, Thank you for the response. I've pulling hair for something simple(I think). But, I wanted to add that the compressor is a three stage compressor, which spits out the air at 225 deg C. Is it safe assume then that at exit the humidity is 100%?

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...
