how to calculate the maximum flow velocity of flammable liquid?
(OP)
Dear all:
I'd like to ask you a question: how to calculation the flammable liquid DMC(Dimethyl carbonate CAS No. 616-38-6) which MSDS is attached, it's designed flow rate is 12.5m3/h, DN40 304 stainless steel pipeline which velocity is 2.7m/s, but there is an opinion which is velocity should not be high than 1m/s for flammable to aviod static electricity, i looked up API2003 and NFPA 77, it mentioned that VD<0.38 (V is velocity, D is diameter) is OK while under on circumstance is higher than 7m/s
My question is how to calculate the maximum velocity for flammable liqiud? for example, how to determine the maximum velocity of DMC Dimethy carbonate? thank you a lot!

A lot depends on the ability of the static charge to dissipate from the liquid and avoiding any means of either creating a spark or getting an explosive atmosphere.
I'd never seem that equation before but the number sounds right to me.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

3 m/s the generation of static electricity by acrylonitrile should be minimal, but plant handling this chemical should be earthed."
is this means, for acrylonitrile this chemical, the velocity [b]should not be higher than 3m/s or at least 3m/s? thank you a lot!
