How is the chimney effect of exhaust stacks calculated? !

2017-11-07View Original

Thread Content

Within an altitude of 2000 m, for every 12 m increase in height, the atmospheric pressure decreases by about 1 mmHg (133 Pa). For a 15m high exhaust stack, the atmospheric pressure difference between the top and bottom of the stack is approximately 166Pa. So when designing the exhaust stack, does this pressure difference need to be taken into account? !
