I basically want to carry out analysis on the current rating of the lines (some of the network is mixed conductor), voltage drop on the network and what is best method for a generator connection.

Hi, I have a couple of MS Access databases comprising of the locations poles, switches and equipment of some MV network. I want to use software to take the information in the database and analise the network graphically (maybe super impose the network on some maps using ArcGIS) Can you...

Hi, I have being doing a little research on medium wind turbines for a masters thesis. Mainly around the 500kW mark. I have come across a wind turbine produced by EWT in the Netherlands. It is a DW-52. When I look at the power curve data I see that at 9m/s wind speed at the hub it produces...

Hi guys, I have just started a new engineering job (about four months, fresh graduate) and have also start studying to become a tax advisor. It’s a three year program, the study that is. The tax exams touch on accounting, law and how companies operate. I hope to use the skills I learn for the...

Thanks for the advice guys. I am turning towards the start-up as the product is great. They are already expanding. They hope to double their work force in the next six months or so. The big international company offers, probabily a better wage, more travel and stability, but the work will...

The fuel i would like to use is Aviation gasoline with hydrogen peroxide. I plan to use regenerative cooling by building a cooling jacket around the chamber and pumping the fuel through it. I was thinking of film cooling but it seams abit more complex. the mission plan is simple, its basical a...

Thanks for the input, but how about using copper instead of aluminium

Hi, I am thinking about building a liquid rocket engine as a project. I have come up with a plan to cast the thrust chamber out of aluminium in the "full-mould" process. For those of you who do not no the process, its basical; you make the mould out of expanded polystyrene, cover the mould with...
