Thanks What I meant to ask was are the calculations the same when you are installing in the southern hemisphere and thus the panels face north. Apologies for the confusion

Hi I was wondering what the method/theory is behind selecting the size of an anaerobic digester in order to fuel a 500kW cogeneration unit? Any ideas? Thanks

Hi Does anyone know any good reading sources that help with the following calculations: 1) find the optimum photovoltaic inclination from the horizontal 2) find the radiation for this pv panel when you know what the global, direct and diffuse radiation is Thanks

Hi Is there a way to create/estimate the hourly electricity demand data of a system by just knowing the daily peak load (and at what time this happens)and the total electrical consumption per day? A good estimation based on a statistical technique sounds like a good start! Cheers

Hi Using the miscanthus energy crop as a biomass with thermophilic conditions. External environmental conditions at average UK. Just to get an idea of the process behind this calculation and what equations/models are used. Thanks

Hey guys Does anyone know how to calculate the biogas volume of an anaerobic digester depending on the type of biomass fed in. Are there any good sources on this specific question? Thanks

haha thanks for the sarcasm SteamKing :P 1) I am working with gas turbines for power generation and not thrust generation. 2) I was basically asking for the main losses within the cycle and how to quantify these losses 3) The reason being is because I then need to calculate how much torque my...

hey do you guys know what the equations for efficiency, work done and losses are within the brayton cycle. I am trying to do a backwards model starting from the size of electrical generator I need and thus working towards what capacity gas turbine, pressure ratio and inlet temp I should have...

thanks! I have not been able to find a schematic of the brayton cycle with all the necessary equations. It would be extremely useful for me if you could help me construct one with the relevant equations of Temp, Pressure, efficiency, work done, power and efficiency. All I currently have...

Hi I am trying to model the Brayton cycle in a gas turbine that is used for electricity generation. My main aim is to be able to fully power the x amount of daily electricity load of a building using this machine. In order to do this, is it correct to do a backwards model and find what...
