I am selecting the operating temperature for some equipment e.g. pumps inside a building.
The external temperature is 105. The plant building is ventillated mechanically (and no A/C) with intake at +2m and outlet at +15m. There is are several industrial furnaces inside the plant on the ground...
Dear all,
The total head (m/ feet) for a given pump curve, is it always in pressure atmosphere or pressure gauge?
Eg. reference the pump curve Total Head H in Page 8. No atmosphere or gauge is stated. So which is it, A or G?

Can more knowledgable persons please explain because I am not very familiar with details of valves and its dimensions.
For pneumatic actuated valves, would the face to face dimension be the same as a manual valve for a given type of valve, e.g. butterfly type?
I need the information very...
Dear all,
May I please check with the Engineers in the USA and in Canada, please. I am currently discussing an offer (scope: Process, mech, EIA and equipment for a dryer plant) with a supplier from Canada.
The supplier informed me that he will NOT submit any design calculations to support his...
Please suggest information on necessary hook-ups that detail the mech/instrument requirements for a process plant.
Sampling needed for flow, pressure and temperature, and fluids: superheated steam (40 bar/ 410 deg. C), saturated steam (270 deg. C), condensate, feed water, and flue gases...
I am pretty rusty in Thermodynamics, and I have spent time reading my old texts, but no luck to find a classical text-book solution:
What will the resulting fluid properties be if, 1200kg/h SH steam at 0.8 bar(a) and 340 deg. C is allowed to flow into a exhuast steam duct kept at 0.8 bar(a)...
Hi all,
This might be slightly off-topic:
the water bottle in the hydration belt that I use for running- it is made of a soft plastic. everytime I fill it up, and drink from it, it has an unpleasant taste to it.
What is causing it- leaching? Dangerous and toxic to mankind? :)
Can some...
Dear all,
Currently I have the question on the need for pressure relief downstream of turbine bypass station/ steam conditioning station.
The bypass station (2nos) reduce pressure of 40 bar/400 deg. C to 0.6bar(a)/105 deg. C. The steam outlet (1.5m diameter) is connected to the steam manifold...
Hi all,
I will have a vessel (75m^3) coming up for hydrotest in the winter (-4 deg. C ambient).
The material is A516 Gr70 with thickness of 15mm. The MDMT for design is 5 deg. C.
My contractor has explained it is okay to test in the winter without any additional measures.
We are aware that...
Hi,
Can some of the more knowledgable folks please point me in the correct direction.
I would like to size a steam header to reduce the pressure of the recovered process steam (saturated condition) at 600psig to 20psig where it is returned to the deaerator.
The 600psig steam are from 3...
Hi all,
Decided to seek some informed views here
I have been in both industries: environmental engineering dealing with trash inceneration (current) and waste gas cleaning, as well as offshore O&G driling and production (previous).
O&G is interesting for the dynamics and people and challenges...
Please excuse me from asking what maybe a basic question:
Can an EN designed vessel be connected to piping designed to ASME B31.3. Assume the connection is a flanged nozzle to DIN. The design engineer then designs a suitable mating flance to ASME with the DIN flange dimension.
What issues can...
Can anyone point me to references that provide information on the highest allowable temperatures a worker can work in for a sustained period of time?
I have a case of high indoor temperature in a factory due to high heat losses, and the temperature may reach 130 deg F/ 55 deg. C. I was told by...
Can you please recommend leads for rough Vacuum service? The valves, ranging would be gate or globe valves, sizes of 8-12" for steam condensate service, sub-atmospheric pressure, ~80 deg. C/ 176 deg. F.
All suggestions greatly appreciated.
In my new field of work and company, I sense the need for an experienced and knowledgable mentor to guide me. Please advise on how to actively find a mentor external of one's company? What are the avenues for this.
Also, how many of you actually mentor and receive mentoring in today's time and age?
I am in the process of setting up a knowledge archive system on my company servers.
Among material I want to storing/ archiving: Engineering calculation sheets, drawings, case studies, results of plant comissioning and monitoring, vendor data, company and customer specifications, Codes and...
An interesting incident happened to me- in talking to my younger, new colleague who was obviously eager to please, I mentioned the previous area of work she was in (similar industry).
Was I suprised when she launched into it and... pulled out the drawings of the design to show me highlighting...
Dear Forum Members,
A temporary Worker's Accommodation is being provided in the Middle East desert environment , housing initially 500 workers to a peak of 1200 during a 3 year period.
Waste water from toilets (black water), grey water (showers, washing machines, etc) and kitchen waste water...
This topic came up as a point of discussion among the engineers in my company.
We are looking at suitable parameters for the steam turbine exhaust pressure vs. air cooled condenser design ambient temperature operating in a desert environment. Estimated steam flow is ~200ton/hr, 400 deg. C and...
In cases when something does go wrong, e.g. calculations performed wrongly, specifications missed out, or drawings not properly checked and it causes some problems in the shop, what is the typical apportion of 'blame' or fault?
In my first company, I was told: Originator (typically an engineer)...
