Hi,
I'd like some opinions about guaranteeing easiness of operation of a siphon connecting two ponds.
The installation is at sea level for irrigation, the configuration is:
- there is an existing pond of 600,000-cubic-meters of water capacity and 8-meters of water depth. This existing pond...
Hi, everyone.
I'm looking into the requirements that I should make to the structural engineer for the installation of a magnetic chiller in a roof.
After looking into thread507-299291 I'm understanding that if he provides a 6'' maintenance slab and I specify that the equipment is provided with...
Good day, community:
I'm part of a team that is designing a fire-protection system for an airport terminal building. Other parts of the fire-protection system (like hangars and maintenance workshops) are being taken care of by an independent system.
We are having issues in defining if it is...
Good evening, community:
I'm reviewing the HVAC design of a chiller plant in the basement of a 30-floor building.
The main equipment present in this room are:
- Chiller / 360 ton / 351 kW (x3 units)
- Primary loop pump / 1512 GPM @ 60 ft w.c. / 30HP (x4 units)
- Secondary loop pump / 2268 GPM...
Good afternoon Comunity,
I'm designing a storage tank for Sodium Hydrosulfide (NaHS) 45% solution for a Mine in Peru. Due to the required storage temperature (as pointed in http://www.genesisenergy.com/assets/_RefineryServices/Technical_Guide/Technical_Guide_10_31_11zip.pdf) and the site...

Dear community,
Recently I received a BOM for a Power Plant designed in South Korea. I have an issue with items described as "ASTM A106-B CS SMLS PE XS/80 (PE.C)" or "ASTM A106-B CS SMLS BE XS/80 (PE.C)", I have never used the (PE.C) descriptor and I am ignorant of its meaning. I've tried...
Dear community,
I'm in doubt in the following aspect of a Primary Variable Flow CHW system :
The minimum flow of CHW through the chiller is provided by the lowest speed of the pump. Also, the chiller has a minimum load protection.
My doubt is if below the minimum cooling load the chiller...
Hello, comunity:
I'm in the middle of the calculations of the columns that support a Cone Roof.
I'm having problems deciding for the k factor to compute the slenderness ratio:
- I visualize the contact area of the roof as a FREE boundary condition.
- I can't decide if the connection with the...
Dear comunity:
I'm dealing with the task of justifying the use of mitered bends that were field constructed without consideration for what is established in ASME B31.4-2009 404.2.4.
The pipeline starts with a manifold connected to 4 Vertical Centrifugal Pumps each one rated to 585m3/h @ TDH...
Dear community,
I'll appreciate your oppinions in how a downhill gravity pipeline is being analyzed.
The pipeline has changes of internal diameter and slope, altough it always is going downhill. The pipeline starts in a tank and discharges to a pond and has a flow requirement.
1) We analyzed...
