Jul 16, 2007 #2 Feric Mechanical Dec 8, 2005 137 Hi there: There is a rule of thumb rule that can be applied -- it is up to 5% of the combustor inlet pressure. http://engware.i-dentity.com Upvote 0 Downvote

Jul 17, 2007 #4 Feric Mechanical Dec 8, 2005 137 astro28: Most of the time it is an emperical relationship. The best thing is to go with a rule of thumb. Later on, if you have the capability and equipment, you can measure it. Also, if you know the equipment vendor, check with the vendor -- they should be able to provide you with some tables and charts. Today, the vendor might have it on the web site ...

Jul 17, 2007 #6 Feric Mechanical Dec 8, 2005 137 astro28: Well, that is the reason why I have been referring to the rule of thumb approach. Anyway, the precise pressure loss calculation should not slow you down in your work as long you know how much it is ... Thanks, Gordan http://engware.i-dentity.com Upvote 0 Downvote

Jul 30, 2007 #7 gtsim Mechanical Aug 10, 2005 90 You can try Gas Turbine Combustion by Lefebvre or Gas Turbine Theory BY Saravanamutoo, Rogers and Cohen. They cover it quite well. Upvote 0 Downvote

Aug 8, 2007 Thread starter #8 astro28 Aerospace Jul 16, 2007 4 Actually I tried and they do not help, because these formula are too general. There is no correlation for static pressure at the hole exit to the static pressure downstream (in the flame tube). Upvote 0 Downvote
