My working place has conveyor to transport bottom ash from scrapper to bottom ash silo. Currently this transporting system has problem about bottom ash that carried back. I read in this article ...
Hello.. I am fresh graduate of mechanical engineering and has high interest in Pressure Vessel design (to prepare if I work in EPC company). I still hard to understand designing Pressure Vessel support. I've read 2 books, Megysey's Pressure Vessel Design Handbook and Dennis Moss's Pressure...
I've read Moss Pressure Vessel Design Manual about design of Vessel's Saddle. To calculate minimum width of saddle at top, Moss suggest to use formula like in my attachment. But the problem is, what is Fb and h ?
Moss said that Fb is allowable bending stress, how I get it ? is it same with...
Hello guys.. so i have homework to design heat exchanger. Inner diameter of the shell is greater than 24" (lets say 27" ) so I can not made of shell from pipe, i have to use plate. How I select type of flange, I mean its dimension and rating ? because ASME B.16.45 only provide flange until NPS...
Very need help with this problem. Properties which is known are fluid inlet temperature (both tube and shell), 1 shell pass and 2 tube pass, surface area, mass flow rate. With the unknown are overall heat transfer coefficient U and fluid outlet temperature. I want to compute fluid outlet...
Tube in heat exchanger is under internal pressure and external pressure. Fluid in the tube is water. How to calculate the minimum wall thickness ?
What formula must I use ? I confuse is ASME 8 Division 1 which I have use or the boiler formula ? or maybe using asme B31 ?
And how to use that...
I have problem when calculated dirt factor using Kern Method. From Kern Method we will get calculated dirt factor using formula (Uc-Ud)/(Uc*Ud) and allowable dirt factor from TEMA table. My question is, at what condition the heat exchanger need to be cleaned. is it if the calculated dirt factor...
I have data sheet of shell and tube heat exchanger said that the dirt factor or fouling coefficient if 0 for both shell and tube.
I want use kern method to know the heat exchanger need to be cleaned or not (rating problem). In rating problem it must compare calculated dirt factor and allowable...
Hello.. I need help because i want to calculate shell's convection coefficient. but this exchanger has 30 degree pitch tube arrangement. I've read Kern's Process Heat Transfer book and Coulson's Chemical Engineering book but they only provide for 60 degree and 90 degree pitch tube arrangement...
Hello. I have problem to select SA 36 for my saddle design in PV ELite 2017. Is PV Elite doesn't add SA 36 to the list of saddle material ? or SA 36 has different name in PV Elite 2017 ?
Thanks
Is it based on the formula (what formula?) or based on the simulation (maybe the greatest stress ?) or is it based maximum allowable stress of the material (S) ?
Thankyou
