I have 1" dia pipe of 100m length , at the inlet Air is at 5kg/cm2 pressure, I need to know the maximum flow of air (m3/hr) through the pipe, outlet pressure is 2 kg/cm2 temperature is 38C.


answer of the question from AYAZUDDIN

In such condition the velocity of air increase up to the rule of thumb suggested velocity 66 ft/sec,
analysis express the velocityis 122 ft/sec but in that scenario max. flow would be 56.5 m3/hr, which
increase in pipe due to small line size which is 112.4 m3/hr. as far as my suggestion of current situation
you must increase ur line size because velocity is very high
