Resist the tendency to become bitter, as justified as you would be. Hang in there. See if you can attend some job fairs for a range of companies you'd like to work for. Meanwhile, go through your Uni textbooks in your free time and pick up on skills that you think may set you apart from the...
Flow has increased by a miniscule amount from 3.12mmscmd to 3.15mmscmd
Offtake at B is controlled by B compressor process flow-discharge- speed controls
For long term operation, better to automate and transfer this pressure control function to a PIC-PCV at inlet to B compressor station. PCV...
In most heat exchangers operating on steam, thermal duty modulation at each unit is by throttling the steam supply to the HX - this reduces the steam side pressure in the unit. All the steam trap does is to drain out the condensate when it is subcooled somewhat or when static differential across...
Your calcs so far cannot predict if the steam traps will be overloaded with high backpressure - calc stops at velocity estimate. Two phase flow pressure calcs can be complicated and risky especially in lines with risers. The calcs say that sizing case pressure downstream of existing steam traps...
MOV can be gate or ball or butterfly type valve with electric on-off actuator. There are variations within each of these types to suit specific applications.
MOVs' are not pneumatic actuator operated valves
Rod or bar type baffles are used to eliminate dead or stagnant flow zones on shellside - there is a description of these on page 11-42 in Perry Chem Engg Handbook 7th edn. Must confess I dont know how these look or work though.
Thick sludge in this sump pump pit ? Must have bunged up the intake with no flow while pump is running. Overheated oily sludge. Time to clean out this pit. See if you can raise this pump from 200mm above pit bottom to say 500mm to give you a bit more room to hold semi solid sludge before it...
I prefer a flow through the expansion drum system
a)It allows for better disengagement of vapor bubbles that may be in the HO return stream from any high pressure leaks at user heat exchangers tubes or tube-tubesheet joints. So HO pump does not see vapor bubbles in its feed
b) With a through the...
In a well designed and commissioned closed loop cooling system, biocide and corrosion inhibitor injection would be a preventative measure. How did SRB get into this TW cooling system in the first place ?
What is this "treated water" ?
In general, shutdown and startup operations on any rotating machine place heavy loads on the shaft bearings. And dynamic loads on these bearings are also higher when running at higher speeds. So it is good practice to slow the machine down, (and bring it down to low loading from a process...
The cost of labour spent by engineers on this thread has now well exceeded the cost of this hot wire anemometer type flowmeter, and we are still nowhere near a reasonable estimate of this flow.
If you cannot add an internal heating bundle, then install an external kettle type (TEMA AKU or BKU ) heat exchanger with LP steam or similar as heating medium on tubeside. Draw off vapor only from vapor side of kettle to user. Operate the kettle on constant level control with LCV upstream. And...
Pls note that for low vapor pressure liquids, folks tend to interchangeably use metres of water liquid column as metres of actual liquid in service for NPSHr. This simplified approach can be a risk when operating with volatile liquids.
Preferably, with volatile liquids, you should insist that...
Radioactive decay of large unstable nuclei often produces EM waves where mass number changes and binding energy per nucleon changes. But to do the converse (absorption of EM waves) would most likely require crossing enormous energy barriers for the EM waves to overcome the binding energy in the...
I dont know if there is a "resonating frequency " for a radioactive nucleus. If there is such a thing, and if this frequency is in the X ray / gamma ray frequency range, then may be what you say may work.
Typical thermal eff for an API12K water bath heater would be about 60%, so fuel gas demand, at 43kW heat transfer duty, would be 43/0.6 = 72kW.
Both heater and tank would have to be insulated - 2-3inches of hot ins should make heat loss to ambient minimal.
Suction flow, for a given venturi design, would be a function of suction pressure, suction gas temp, motive gas pressure and motive gas flow. The influence of the latter 3 is not shown on your graph.
Trying to figure out flow pulled through a venturi can be dicey. At best, flows estimated will have a large error.
Suggest use of a hot wire anemometer for this - not expensive.
