ok, might have cleared things out in my head. if the heat exchanger has a pressure drop of X then the flow out will be 20 gpm through the 10LF 1" pipe. So all i really need to know is the pressure that is required to flow 20 gpm of water through the 1" pipe. This seems really low but 1.6 psig...
Not sure if i have enough data to tackle this one. I have a 1" pipe with water at 60 psig going into a heat exchanger. The heat exchanger discharges water at a flow rate of 20 gpm. I am unable to access the heat exchanger, but i know its there. How do i determine the pressure at the...
Looking to determine the remaining capacity of an Immersion Heater:
480 V
90 kW
1-3 Phase
. The readings gave 67 Amps
Any ideas on how to determine the remaining capacity of this heater?
I am not able to find the allowable stress, ksi, at 572 F for this material. Any tips on what i am missing out on. Is this comparable to another material and i am just not aware of it?
Thanks
pipe is going to have 4 inches of insulation. that should have been included. i can solve for how much heat is lost thru the insulation. the btu/hr requred to keep the steam at at the given temp is where i am stuck
this pipe is not unique. there are others that are jacketed that have not clogged
question on the film coefficients. not sure which one to use for the steam. still looking into that one
well it is steam traced right now and it is not working
need to keep the pipe as hot as possible to keep it from becoming fouled
think i am making progress though
basicly breaking it into two parts. heat lost thru insulation + {q=UA(dtm)}
still working on it but seem to be moving forward...
guess i was looking at it differently. my thinking was to look at this as a heat exchanger with heat coming from the vapor in the jacket to heat the steam. then add in the heat lost through the insulation from the vapor in jacket. what you are saying is to only deal with the heat loss from...
I threw air on there as this pipe needs to be evaluated using different flows, not just steam. This pipe is already insulated and that is not enough. Need to keep the high temp until exiting the pipe
So there is an exhaust pipe that releases steam at 326C. This pipe needs to have a jacket placed on it to keep the steam at an elevated temp. so that particles to do not clog the pipe as they cool. This is an 8" pipe that is 10' long. I am trying to figure out how to set up an equation to...
This was built about 60 years ago so the "S" could mean any number of things. I just don't know what those are. Silicon steel sounds like a good starting point. Will do a little research.
looking at some drawings and there are a bunch of old steel on here. There is 10WF21 and 10WF21-S listed and I was wondering what the difference was. Any ideas?
only known force at this point is reaction force due to discharge. the thrust of the discharge would be the force. this is calculated out to be 634 lbf. what i am looking to do is design a dip tube with gussets coming down a few feet to limit the stress to 12,000 psi on the dip tube. i can...
well, the pipe will be discharging a mixture of vapor/liquid. so assume all vapor at a rate of 25500 lb/hr. this will shake the pipe some. but, the plant has has issues recently with dip tubes breaking and wants a design that remove any worries. so, the thinking is define a maximum stress...
