if i have the equation for enthalpy of water overall enthalpy = enthalpy of formation + enthalpy of water 1800k - enthalpy of water at 298k what is the value of enthalpy of formation is it enthalpy of formation of water as gas or liquid? enthaply at 1800k would that be enthalpy of...

If i am trying to burn a fuel in air am i right in saying if i have a higher temerature compared to a lower temperature of air, the higher temperature air has more moles of air to burn than the lower temperature air for complete combustion to occur?

the device is use to introduce some form of liquid into the flow i haven't any specific specifications for the design just thinking about the shape trying to bea s aerodynamically sensible as possible.

yes the shape is always going to be impinging the airflow the velocity of air varies from 100 meters per second up to 300 meters per second

I am trying to minimize turbulence so i would like the Reynold number to be lower than the turbulent value of reynold number.

I have a flow acting perpendicular to a shape ie an airfoil however i don't think an airofoil is the best shape for the flow not to recirculate too much was wondering if anyone has any ideas? please view my attachment for basic drawing of the problem thank you engineering

Please see my diagram the diameters of the hold are fixed it has a fluid running through it being injected outwards. The diameter of the holes is fixed. the tube shape chamber has a free stream velocity flowing round it can be assumed to be air. need method of calculating pressure drop and head...

My fluid dynamics is rather weak and i was wondering if someone could please tell me how to calculate dynamic head of the flow in the a tube and how to calculate pressure drop of a hole in a tube? Some formulas would be handy thanks engineering

Thanks for all the help guys much appreciated. also cheers fred ill look over these two pages looks like interesting stuff thanks for taking the time to locate this information for me. Engineering

Thank you for your reply I have studied fluid dynamics. Why would pressure changes in the pipework be of importance? (by that i mean what happens to the flow of air at different pressures?) I think it may affect the density of the air traveling through bend but i am not sure. I understand that...

I am only dealing with gases at the moment I assume your definition is still valid. My problem is reduction of turbulence in terms of air flowing through a 90 degrees elbow. Would introductions of internal bends be a way of reducing turbulence? Please view my sketch I apologize in advance for...

hello I wanted to know what happens to the level of turbulence when air pass through a 90 degrees pipe bend (where in the bend turbulence is greatest). I want to design a pipe to reduce turbulence through 90 degrees. I know its obvious that level of turbulence increases but i am puzzled as...
