    Back Pressure of Two Compressors with a Spray Nozzle

    Hi, Ed and Latex I did try to join their outputs with a small tank due to limtied space. Oddly, the air flow rate and surface temperature of both compressors increase a lot more. Perhaps, I should put a baffle inside of the tank to smooth out the flow and maintain its flow rate. I would like...

    Back Pressure of Two Compressors with a Spray Nozzle

    I am hoping I can get some help from your expertise. I am currently using two small diaphragm air compressors connecting with a Wye-fitting and that will be the main air source for a spray nozzle. The outlet of the Wye-fitting will be connected to a nozzle, which has a very small hole in order...

    Water Tank Heat Transfer with Various Scenarios

    Hi all, I have a simple question regarding to the heat transfer of a heated water tank with three scenarios First scenario: Air velocity, 88 ft/s at -20 F, is blowing parallel to a 8' x 16' cylindrical tank filled with water. The tank is 1/4" cold-rolled steel without any insulation. The tank...

    Books or Design Guidelines about Rotary Vane Compressor

    @51stovebolt I would want to design the rotary vane compressor itself instead of selecting one.

    Books or Design Guidelines about Rotary Vane Compressor

    Hi, I am sure there are tons of books out there on designing rotary vane compressor. Can any one recommend me a couple of them? I am looking for more of engineering and design guidelines of rotary vane compressor head specifically. Anything other than the books is also helpful. Thanks a bunch.

    Protect your own design

    @Ron Believe me, I wouldn't want to consider to ask anyone online for an opinion if it was not ethical. As unethical as it sounds, I really think it is necessary to be careful about this because it's about professionalism. If I do not know the basic rules of engineering laws, maybe years of...

    Protect your own design

    @KENAT What is the definition of "work resources"? If I used the information from ASTM standard from my own purchase, and also the company has a copy as well, will that consider the "work "resources"? Using internet at work for research purpose, will that consider "work resources"?

    Protect your own design

    Is there a clear source where I can refer to for protecting my own design from the company I work for? It sounds kind of strange why I ask this. If I do the design work in the company but nothing has been manufactured yet, will the design still be the company's property? I would like to know my...

    Cylinder Sheet Metal Flange Bend

    @berkshire I have tried your method and i am not too lucky afterall. @CorBlimeyLimey I have tried that as well but i don't think i can create a flat pattern on this sheet.

    Cylinder Sheet Metal Flange Bend

    Hi, All Is there a way to create a flange on the tab from a cylindrical sheet metal? I could have created a part for extrution but it won't let me flat the part for the strip machine to bunch it out. Your file's link is...

    Airflow Pattern

    Kenat, The application that I am working on is to use the advantage of air pattern to create or furnish better combustion for heating. The setup is really similar to jet engine compressors with vanes. something like this...

    Airflow Pattern

    Hi, Everyone Is there a textbook or a website that I can study about the behavior or airflow pattern? The idea is simple: using a blower/fan on one end of a pipe with a deflector (blade/propeller) in the middle and creating whirl airflow pattern. In other word, pressurized air is forced into a...

    Quality of Atomization depends on......

    Compositepro thank you for the explanation on the relationship between pressure, flow rate and atomization. You were right on the power consumption and the liquid flow rate and droplets. When I start to spec out the compressors with same voltage and same pressure output, it gives you...

    Quality of Atomization depends on......

    To examine the performance of an air compressor for atomization quality, the air compressor which is rated for 15 PSI with 18 LPM is used. For what the compressor is rated, it creates good form of atomization (mistt like). The air output can be controlled by adjusting voltage (DC air...

    Quality of Atomization depends on......

    This question is specifically focus on siphon air atomizing nozzle, which creates atomization with compressed air. When compressed air enters the nozzle, it creates suction and draws liquid for atomizing process. Since compressed air is the only driving force for siphoning the fuel and the...

    Definition of Heat Outputs

    IRstuff That was the same question I have when I kept hearing people saying this phrase. I guess in this application, the heated water is used from the boiler to provide both hot air and hot water. So, my guess is that true BTU output of this boiler is the BTU outlet from the water side instead...

    Definition of Heat Outputs

    The amount of energy input provided by any type of fuel can be determined by the following equation: Qin = HHVfuel * mf,actual which this equation is based on based on fuel consumption and energy value. Efficiency by definition can be generally expressed as this: Eff (%) = (Qout / Qin) *...

    Definition of Heat Outputs

    IRstuff When we test a boiler, we have an emission analyzer which measures the O2 percentage, CO level, excess air, flue and net temperature, and efficiency. You are right that about the importance of fuel consumption. The CSA provides formulas and information about heat input and output which...
