how to calculate and measure the flow of compressor without any instrument in practical condition?

Fix a baloon to the out let of compressor, this will give you the volume of air filled in a particular time. Now dip the baloon in a container of water and measure the volume of air in baloon. Divide the volume of air by time that gives you the flow. The volume of baloon can be best measured by difference in volume of water in a container.

Your question is a little vague so I'll list a few applications. Aircraft instruments, piston and turbine engines, barometers, steam engines,

Unless you have a way to measure the output torque, any method you use will be an estimate. \n\nIf all you want is an estimate and there is a way to determine or estimate the load requirements of the driven equipment then you have a chance. \n\nAs an example:\n\nIf it is driving a 100 gpm water pump with a known efficiency and flow rate you can measure the differential head, then it is possible to estimate the load requirement of the pump and therefore the output of the motor. Be careful, efficiencies and flow rates can vary with head requirements.

Well this isn't always easy to figure out and what I do is track the flow backwards till I hit the nearest data store then watch some data as it flows from the data store to each process checking the inputs and outputs. Your miracle is going to be the process which is taking no input but producing output.\n\nThis is what your data flow diagram is going to show you, where the miracle is occurring. You may need to go up one level to a more generalized overview of the system and find the component which is outputting without inputting. \n\nAnother way is by outputting some debug data before and after each process and comparing it to known data to see if it is working correctly. If you see an output message appear without the input message, then you found your miracle.\n\nStart with the general area you think the miracle is coming out of and watch data as it flows through it. That is the best I can tell you without actually seeing your DFD. \n\nHope it helps you out! Good luck!

u will find lot of papers regarding air compressor in this site\nhttp://air-compressor-guides.com/

Theoretically you can by compressing normal air to a tank, then you will have a full tank with a 8 bar pressure, then find another tank, do it again as you do with the first tank, and now you have two tanks with same 8 bar pressure.\nNow connect one of those tank to the inlet of the compressor and the other to the outlet of the compressor. Run the compressor, and you will get the tank that connected to the outlet of the compressor a higher pressure than 8 bar. Do it repetitively and by the end you will have a tank with 200 bar pressure.\nThis technique is used in multistage compressor.\nBut practically don't do this. Why ? A compressor is designed with a working pressure. and of course has limitation on strength.\na 8 bar compressor is much less weaker than 200 bar compressor, so with the tanks, a 8 bar tank is much weaker than 200 bar tank.

the compressor is used to compress cold air to be used in the cooling process of a/c. you lose very little coolant in the production of a/c.it takes the humidity out of the surrounding air and that is why we see the outside of the a/c drip water. that is the water or humidity that has been taken out of our environment

I've worked with flowmeters for 20+ years and have never heard of this... what medium are you trying to measure?

I don't think you will find a circuit diagram for a digital water (fluid) meter so easily. But let's analyze what you need to build one:\n1) A flow sensor (a "turbine" wheel that outputs pulses), tricky to build a reliable one by yourself....\n2) A counter,  see http://www.kpsec.freeuk.com/counting.htm\n3) A display, and its driver.\nUnless you want to buy a complete electronic flow meter, like  http://www.rittenhouse.ca/asp/product.asp?PG=1553\nor more "professional",\nhttp://www.flowmeters.com/products/index.cfm?task=cat_prod_page&master=yes&master_cat_id=29&cat=yes&cat_id=163#29_163

You need to be a bit more specific about which quantities you are trying to determine.  "Flow" is not a quantity to be calculated.

weigh the graduated cylinder full with water.\ninvert the cylinder (still full) in a tub of water.\nblow bubbles into the cyliner to find the volume of the air you blew in.\nremove and reweigh the cyliner.\n\nit may be a little tricky, but it's not too bad.
