Hi
I have a theory question that I hope you can help me with. I'm going through the derivation of the major and minor system loss in natural ventilation and I have the major and minor losses in terms of the density: ![]() However, when I look into these I find them in terms of gravitational acceleration: ![]() How do you switch from one to the other? The only way I have been able to find to do this is by using the specific weight: ![]() But as this is not in the original equation, has it been assumed negligible as it is so small, therefore making: density = 1 / g Here are links to the pages I used on EngineeringToolbox: Natural Ventilation: http://www.engineeringtoolbox.com/na...ion-d_122.html Minor Losses: http://www.engineeringtoolbox.com/mi...pes-d_626.html Specific Weight: http://www.engineeringtoolbox.com/de...ity-d_290.html I hope you can help. |
