Quick question about threads in a working drawing.
For my semester project, I made a beam-type steam engine in Autodesk Inventor. I thought it would be cool to add real threads to my assembly, so I downloaded the coolorange (auto thread modeler) addon.
It looks really nice with it all assembled whotnot, but my professor doesn't like the threads showing in the detail drawings. Is this frowned upon in the industry or is it his personal preference? I have to go through each part and get rid of the threads now, which is a hassle...
Thanks,
Question on calculating flow velocity and selecting orfice size
I have a machine that has a square tube header fed from a 4" water line at 20 PSI and around 65F. The header then has 20 orificed outlets that feed spray bars. 4 outlets feed each spray bar (the spray bars are a rectangle with a water line coming in each corner. Each spray bar has a hundred or more (depends on set up) holes around .125" (also depends on setup/product). my goal is to get around 15fps velocity from all the spray holes at 200gpm (measured back in the 4” pipe) and 25 fps at 360gpm. I have been playing with Bernoulli’s equation and various formulas derived from it that I have found on sites of companies that build or sell spray systems and components, but I don’t think I have all the data I need to calculate the velocity of the sprays. I do not have a good way to measure pressure drop across those orifices. Has anyone done something similar, and do you have formulas I could use to get the velocity at different orifice sizes?
Basic Spur Gear design/formula help.
Designing a prototype for future manufacturing. I have referenced 4-5 different formula pamphlets etc. over the last week or so on Spur Gear design and ratio calculations. I have made an Excel spread sheet with the pertaining formulas embedded in the cells for personal improvement of understanding and future simplicity, yet have no way of verifying formulas etc.
- I'm looking for some help with comprehending the formulas.
- Looking for some (known) values of existing spur gears so I can (verify) my own knowledge of the formulas against them.
Is there someone willing to spend some time working with me on this?
Thank you for your help.
Is this gear possible?
Does a gear exist that would allow the motor to drive two different sets of gears depending on back-driving resistance? In other words the gear would have two states:
1) There is no resistance against the gears/motor => the motor drives the high speed gear and the high torque gear remains free to rotate
2) There is resistance against the gears/motor => the motor drives the high torque gear and the high speed gear remains free to rotate
In both of these circumstances the gears should be non back-drivable so that the system can lock without the motor maintaining a torque. I'm an engineering student working on a prosthesis project and so any knowledge/experience/advice in this area would be greatly appreciated. Thanks!
Simulation help
Hello, I need to find a way to simulate a pin that pushes down on a leather sample and causes the leather to be compressed on the pressured region. I need to analyse the time for the leather to return to the original form from the compressed form. Can anyone suggest me any software that can do this? Is it possible to use ANSYS to do this simulation on leather? (I have no experience in using this software) If so, some tips would be very much appreciated. Thank you very much!
Molten Sodium as Heat Transfer Fluid
Hi,
I'm looking at doing a research project on using molten sodium as a heat transfer fluid in a Concentrated Solar Power plant and was struggling to find some informative literature regarding there use so far in other power plants.
I've heard that there has been some use of molten sodium in Nuclear Power plants but I'm yet to find any journal articles or research papers outline this.
I was wondering if anyone has any idea of places I could specifically search to try and find some information on this topic.
Thanks
Is their a Standard for Hydraulic or Pneumatic systems?
Hi All,
I mainly come from a pressure vessel background where vessel are designed to conform with ASME Div 8 or PD5500. I was wondering if there is a similar standard for pressure systems either hydraulic or pneumatic? We want to design a hydraulic system for pressure testing hoses of 1/2" to 1".
Any information is greatly appreciated.
Thanks
Photography or Continue Engineering
I'am a student of mechanical engineering,2 year in diploma.After 2 year I realize I'am not interested in engineering I love to capture nature photo I want to became photographer should I leave diploma and start photography course
