i require 10 bar pressure o/p.but the compressor has only 6 bar max.pressure.how can i get the desired pressur

It is not clear if you mean a mechanical design pressure of 6 bar or a performance limit due to configuration of 6 bar. If it is a mechanical design limitation there is little you can do unless you wish to take the risk of a casing or other failure and the danger that can bring. \n\nI assume this is not a positive displacement compressor because most positive displacement compressors will produce any pressure up to the limit of the driver or the failure pressure of some pressure component. That is the reason for safety relief valves on all positive displacement compressors.\n\nCentrifugal compressors can have their discharge pressure raised my either a larger impeller or a higher speed. You might also raise the suction pressure if that is a option. On raising the speed you must be careful that you do not run into a critical speed or a torsional vibration problems. \n\nHave you talked with the manufacturer? Sometimes they can provide help.

PRESSURE getting less

You better read something on this:\nhttp://en.wikipedia.org/wiki/Pressure

A possible reason this is incorrect is when you plugged your numbers into PV=nRT, you only had 1 mmHg while the problem reads 17.5 mmHg (2333.14 Pa). Also, you are to subtract this from the barometric pressure to get your actual pressure, not multiply (according to the link mei gave). I don't remember doing problems exactly like this, but it appears otherwise you have set it up correctly. The only other thing I can suggest is to double check your units on R. You didn't list them.

If the 20A fuse is the size that is designed for the machine, then something is wrong with the machine.\n\nMost likely, either accumulated dirt, or worn out parts, or both, are causing the load on the motor to be much higher than designed. If you continue to operate the compressor in this way you will burn out the motor. I looked a little bit for on-line info about the compressor you mentioned but could not find it. If it is old, and replacement parts are not available, you may need to replace the compressor.\n\nOne possible transient cause could be a much lower than normal supply voltage - a brownout. If this is happening, the motor will draw more current and possibly blow the fuse. If this is the problem, the solution is to correct the power supply (if it is under your control) or to wait until it is normal again (if it is a utility supply).

you probably have the compression option selected ..

I think the pressure is actually 2.3E5 Pa.  That would make more sense.

hi chuck, \n\n5300 lbs of pressure?  yikes!  hate to be working near that thing if it should blow!\n\nanyway the point of a bladder accumulator is to expand/contract thereby absorbing transient fluctuations in the pressure, right?  so i would expect you would want it to be somewhere near the middle of its range - too empty and it won't be full enough to compensate for pressure dips, and too full and it won't be able to expand to handle pressure spikes.  so somewhere near halfway i.e. 60% sounds reasonable to me.  \n\nthis is one of those things where a calculation of the pressure depends on a LOT of weird variables like the elastic constant of the bladder, the shape of it etc.  your best bet to get maximum damping is probably to just do an empirical trial and error sort of thing.\n\n200 Hz is well within the audible range of the human ear.  G3 on the piano (find middle A, go down an octave plus one white key - that's low G) is supposed to be tuned to 196 Hz, so your 200 cps hum should sound almost like low G.  depending on the amplitude of the pulses you could probably just listen to the pipes, or use a stethoscope if it's too quiet, and then vary the charge pressure looking for a minimum in the hum.\n\ngood luck!

It is filled with air.  It has a circumference of 27-28 inches with a weight of 14-16 ounces.  It should have the air pressure of 8.5 to 15.6 PSI.

BY PRESSURIZING IT AT HIGH PRESSURE & COOLING THE GAS SIMULTANEOUSLY IN LOW PRESSURE

I believe it was around 300 psi.

The pressure on the surface is roughly 14.7 PSI. Each 10m of depth is equivalent to 1 atmosphere. Therefore, at 120m, it must withhold 12 atmospheres or 176.4 PSI.

It is difficult to say without further details, but you could use a centrifugal pump or even a progressive cavity pump.  This is because of the high-head, low-flow you are likely to encounter.  \n\nThe PCP would provide a substantial amount of pressure without the pulsations you would get with a positive displacement pump.  You would have to provide over-pressure protection.\n\nGoogle "filter press" centrifugal "progressive cavity pump"

I get 1.69522 g/L, using constants with the most significant figures I can find:\n\nN/V = P/(R*T)\nP = 101.325e3 Pa\nV = 1 m^3\nR = 8.314472\nT = 273.15 K\n\nN/m^3 = 44.6149 mol/m^3 = 0.0446149 mol/L\n1 mol of F2 = 37.9968 g\n0.0446149*37.9968 = 1.69522 g/L\n\nIf I use 100 KPa (1 bar) as standard pressure, I get 1.67305 g/L\n\nThe difference in the values given in the answer and the "Handbook of Chem. & Physics" is apparently due to the shift from 1 atm to 1 bar as the definition of "standard pressure."\nI think the slight difference in my calculated value and the published one may be due to the fact that when you start getting out to that many decimal places even "ideal gases" aren't totally ideal....maybe I should try the Redlich-Kwong EOS...\n\nOooooops!  I didn't want to do your homework for you...maybe I should erase all this....:)
