I like to know the general method adopted in engineering/design industry to calculate pipe line pressure drop( & pipe line sizing method). Any body help me in this regards with handouts/equations/reference.

If you have send it to my mail id vinee43@yahoo.com

Vinee,
The best reference for performing calculations of the type you describe would probably be Crane TP410 (TP=Technical Paper). This is really "The Standard" for industrial hydraulics calculations. The most universally applied equation would have to be Darcy, which is extensively used (with examples) in Crane. As far as line sizing is concerned, each operating company and engineering company has its own standards for this task. For liquids, staying below a velocity of 10-12 feet/second or 3-4 meters/second is a common criterion. Higher velocities are common for gas flow. Other considerations such as pressure drop, erosion/corrosion, saltation, noise, etc. frequently play a role in line sizing.

Thanks for your reply and do you have Crane TP410, if so please mail me

Crane TP410 is copyrighted material. It is possible to obtain a copy of this paper (Metric or US units) for 45$:

Dear Vinee,

Please try your luck at :

for a free copy of TP410

However many of these calculation sheets /aids are available in most organisations (especially consulting) in their libraries. Manufacturers like Crane even give these as complementary copies to their important clients. Look around in your organisation, ask your seniors!

Thanks i will try it and come back to u

mkhan:

The web site address you posted is a site that distributes illegal and pirated articles and engineering books. Even if it is located in India, it is still illegal and an act that serious, professional engineers cannot have anything to do with. That is why I have deleted it.

This site circulates illegal copies of Crane Tech Paper #410. Whether you want to admit it or not, that is strictly illegal. The Crane book is copyrighted and that fact is clearly printed on the first, cover page that you see. There is no use trying to insult our intelligence by acting as if you (& others) don't know anything about that or haven't noticed this fact. It is still illegal.

What is terribly irreprehensible is the fact that this site is also distributing an illegal electronic copy of Norm and Elizabeth Lieberman's Process book. This is outright STEALING income and revenue from a couple of responsible and worthy chemical engineers who have sacrificed their time and effort to make their valued experience and know-how available to the rest of the world. By stealing and pirating their intellectual property, this site is practicing and fomenting the criminal act of outright theft or highway robbery. It has been pretty obvious to me - as probably to all who have read this thread - that all Mr. "vinee" is after is free, pirated software or information. He/she are unwilling to pay others the rightful price for intellectual property. Such people have no business in the engineering profession.

I would remind ALL engineers who are reading this (especially "vinee") that this could also happen to YOU! If you have no respect for other people's rightful creations or property, than others will have no respect for you or yours. I don't know about you, but I simply refuse to allow the engineering profession to become a DEN OF THIEFS by allowing the theft and pirating of intellectual property.

Shame and dishonor to anyone who thinks otherwise.

Mr Montemayor,

My suggestion would be to make this thread sticky, keeping the OP's question and your answer and deleting rest of the threads.
