I need these values for 400 KVa and 150 KVa plants in order to run an air pollution computer simulation. Thanks!. Volumetric flow is not useful for me,because i don't have any information about flow areas or diameters.
This is a difficult question to answer accurately. The velocity of the exhaust gas is highly dependent on the size of the exhaust pipe. A smaller exhaust pipe, a much higher velocity --- a larger exhaust pipe, a much slower exhaust gas velocity. A 2 exhaust pipe would have about 2.25 times the velocity of a 3 pipe. The exhaust velocity is highly dependent as well on the RPM of the generator. Double the RPM, and there is much higher pressure, and much higher exhaust gas velocity. An attached article mentions that the exhaust velocity in some unspecified gasoline powered car --- and at some unspecified RPM --- is about 240 to 260 feet per second. autolounge /tech/exhaust.html
