Hello- Could you help with gas line calculations? We are thinking of installing gas ranges which require approx 70k BTUs. We have 3/4" gas lines running from the meters, positioned at one end of the building. Our longest building is 225 feet, plus there are bends, friction of piping, etc. See site plan, not drawn to scale. Buildings are built in 1961, we don't have original plans I'm using this website for calcs, but I don't think it is getting me close enough in the ballpark. http://www.engineeringtoolbox.com/natural-gas-pipe-calculator-d_1042.html Thanks Kevin

I have a thermal modeling puzzle that requires special HVAC software to solve problems regarding water evaporating from a fabric, and the cooling effect that has on the material the fabric is bonded to. If you can show the thermal effect of the evaporation on the substrate, and show how that changes with changes in ambient temperature, wind, and humidity, I have perhaps a week of work. Thanks, Ted

I am looking for project manager/lighting auditor/electrical engineer to perform substitutions for lighting audits that I my team physically performs here in the US. Your tasks will include performing the substitution inside our program, one click Cost Benefit Analysis report generation, submission of rebate applications to various utilities, obtaining bids from electricians & tracking of stages of entire project. Please review the training videos and website for the program I use. www.ecoinsight.com You will have to substitute existing lighting for LED Lighting in our catalog at my written direction. (notes that I leave in the line items and program). I am searching for someone who has done lighting energy audits before, and/or has experience managing electrical installations, and/or has used the ecoinsight product before. If you feel your qualified for this position we look forward to hearing from you... Training on use of program provided by company.

The related patent application entitled "System for Harvesting Seaweed and Generating Ethanol' represents a lightweight drone harvesting head tethered by a hose transport system to a much heavier primary ocean vessel. The first part of the concept involves using a much smaller mass than the primary ocean vessel to harvest in a pendulum like motion through the water, thereby moving much less mass than a conventional seaweed harvesting vessel during normal operations. The second part of the concept involves juicing the harvested kelp aboard the primary ocean vessel and then subjecting the juice to high pressure inside a reverse osmosis filter, thereby separating a great deal of the entrained water without losing dissolved solids. Transporting a concentrated pulp to a fermenter and distillery instead of the entire kelp seaweed mass should dramatically improve the efficiency of the system by minimizing energy consumption. I am seeking an individual that can mathematically estimate...

I need an excel file that breaks down the electricity (NOT ENERGY) consumption (2014) for the industrial sector in the following countries: Japan, Brazil, Canada, USA, Chile, Nigeria. The sectors within the industrial sector that must be covered are: Foods and Beverages, Mining, Non-ferrous/other metallurgical, Steel and Iron, Oil and Gas, Chemical Manufacturing, Pulp and Paper, and Electric Utilities. You should also include: Total Electric Power Generation, and Total Electric Power Consumption. The numbers should all be in GWh. You can do this as you want, but I want to understand the values, as well as percentages. The numbers should be found from government sources. Attached is a sample document I worked on, but you can set it up as you think appropriate. If you understood my proposal, please list step by step how you would conclude the job.
