07/01/2010 12:26 AM

Required

Number of known volume of cylinders to be known for the service as mentioned below.
Regulator requirement to be recommended
Arrangement to be recommended

Service Required

The flow of 63 standard cubic feet per hour is required at the tip of the nozzle.
The composition of gas is given in next sheet for high CSR case
Gas is continuously required for 6 hours.
The line size between the cylinders arrangement and nozzle is 2" and nozzle is of 1" reduced at the flange of nozzle
The pressure should be 10 to 150psi(g)
The length of the 2" line is 135 meters

Damn, you just blew right through the rules on homework and copied exactly your assignment to our blog. Well let me show you the official policy on homework as it is stated:

  • Do your own homework. CR4 is not a homework cheat site. While some here might relish the opportunity to sharpen up old rusty skills by working the homework problem, consider this and consider it well. If you cheat on your homework by using someone else's answers, you are only cheating yourself, because the purpose of any homework or other college assignments is to help you learn - by practice, repetition, and self-discovery. (thanks STL Engineer)

We can help you learn, but asking us to do your work for you is just robbing yourself. So please at least tell us how much of this problem you do understand, first. Better yet, tell us what you don't understand of this problem.

Mate this is not a home work this is required for gas compression plant our company is working on . The plant has the supply of fuel gas from it self but at the commisioning stage we cant get that gas so we need the LPG cylinders connected there to supply the gas for making the falme active through pilot.

I managed this info on excel sheet as what is available to me at the moment. But this 63SCFH is the flow when the plant is operational and has the different compostion of gas than LPG. I was also wondering that flow value may be different for the LPG as it is different than what is in the flare datasheet.

Anyways I am no more in uni but yes still student to learn new things and this is not my homework so if you dont mind you can share the ideas. It may be looks like that because of the way I have presented the information. I willbe grateful for productive ideas.

Thanks and my best regards
