It has been great number of years, but if my memory is correct, for line sizing:
(1) 7 ft/s for liquids (including hydrocarbon liquids) unless it a pump suction line, then you may want to use a lower velocity.
(2) Anywhere from 40 to 80 ft/s for gases (including steam)
But there is so much software available for line sizing these days ... why use rules of thumb?

Software doesn't always know its limitations. I'm sure most of the online calculators, for example, are perfectly happy with allowing me to have 120 ft/sec in a gas line.
