What is the significance of the mean arterial pressure?

Pleace what is the ralation between max piston pressure and mean effective pressure of reciprocating compresso?

• I like to know if the compressed air stored in a pressurised tank - by a reciprocating double piston single strage compressor - is it under mean effective pressure in terms the maximum piston pressure of the compressor . and if you say No , then what would the pressure in the tank is equal in term of the piston pressure of the compressor . what is the theoritical method to calculate the output power of the compressor beacause ive a useful research related to this note, if you want ill send to you any think you need , thank you

• Answer:

  The pressure in the tank will be some what less than the maximum pressure in the compressor cylinder. This is due to pressure drop across the discharge valves, the internal passages of the compressor and the piping system from the compressor outlet to the tank. There is no fixed formula for determining the relationship between internal compressor pressures and those at the out of the compressor. There are to many variable such as valve type, internal passage size and configuration, discharge temperature and pressure, volume of air being compressed and one that few recognize. This final one is the standing accoustic wave that exists in the internal passages between the discharge valves and compressor outlet. This is not usually significant in the case of air compressors but can be in other compressors compressing heavier molecular weight gases.
