Thank you both, this was incredibly helpful. Saved me a lot of headaches =)

Thank you very much for the help!! This definitely gets me further along. I'll try to build out my model more before I bombard you with questions. And yes, my energy required was off, I was accidently giving the number I had at 5 T/d. It was 21-26 kW at that flowrate, depending on the constants...

I realize this is a common engineering problem, but after hours of searching/calculating I could use some advice. I'd like to liquefy a CO2 stream (assume 99.9% purity). 5-10 T/d, 20 bar, 40C incoming, cooling to -19.5C at 20 bar. I understand the heat transfer calcs, and it comes out to...

Hi, I'm trying to diagnose issues with an existing water distribution system, and am looking for general guidance on troubleshooting, or even specific advice. There are two storage tanks connected via bottom valves. They both feed a 3" pipe, which then splits to two distribution pumps, one for...

I posted this in a different section, maybe I'll get more luck here... I'm working on the design of two separate rooms, one is class 1 div 1, the other is class 2 div 2. Right now I'm going through the design proposal (layout, flowrates, PHA, etc), however I need to understand the cost before...

Hi, I'm working on the design of two separate rooms, one is class 1 div 1, the other is class 2 div 2. Right now I'm defining the process aspects (layout, flowrates, PHA, etc), however I need to understand the cost before it gets too far along. Does anyone know of good references for...

Thanks for the replies! Bronyraur: I have to confirm, it's possible the previous systems had two separate control valves, one for steam in the top, and another for chilled water in the bottom. Everything is behind a wall and there are no drawings... There is a separate return line for chilled...

I'm trying to size piping to several jacketed tanks (25L, 40L, 60L). Everything will be heated with low pressure steam, and cooled with chilled water. I calculated the approximate cooling time, and my heat transfer value U appears to be correct based on actual results from a similar tank. I...

Thanks!! I guess you've had experience with this? I was also thinking that the spray ball would generate a fixed pressure at any given flow rate. Then I asked the vendor to confirm and the rep told me that was not the case...

My first post, I'm having some trouble with getting the right flowrate/pressure for a spray ball. Rotating spray balls require a flowrate and pressure for optimal operation. One condition could be 10gpm/30psi, while another could be 12gpm/40psi. Is there a way to control both flowrate and...
