Looks like the road to State capitalism. If you don't like economic freedom, you should be supporting the government at the helm of a central planned economy instead of distributed economic freedom. One difference, when a company pays for their own R&D, there is a natural selection that takes...
Even though my statement below has nothing to do with the original posters question, I thought that I would add this to make some folks here cringe. It still makes me cringe to think about it, but it worked.
Years ago, I was involved with the marketing and repairs of Spanish two-stroke dirt...
CarlB, something odd is going on here. When I closed the drawing and reopened it, the viewport problem was resolved. Thank you very much for pointing me in the right direction.
UCSFOLLOW variable did not remedy the problem, but thank you for the suggestion. Locking the viewport is not an option that will be helpful. The problem is with autocad and locking the viewport does stop the automatic change; however, that will not take care of the problem. I am using a 3rd...
I have a problem with one specific drawing where I have created a right viewport; however, if I doubleclick in the port to enter model space, the viewport automatically changes to a top view. If the viewport is locked, no change to the view. This problem only exhibits itself in one drawing so it...
Find valves of similar construction and contact the manufacturers to get the flow coefficients. Look at the spread in the data to determine if you are comfortable with taking the average.
If you cannot find manufacturers with similarly constructed valves, then ask your professor that gave...
SnTMan, not sure how you are going to turn seismic loads into a pressure.
78692Ali, are you sure that you are not being asked to work outside of your depth without a safety net?
CAUTION: Do not use Sch 40 threaded pipe for your grease service. It is not uncommon to use 120 lb or 400 lb grease drums with a common supply pump for large facilities. Pressures can be high and as such, pipe schedule should be based on maximum shut-in pressure.
Contact an A&P mechanic in the area and he will tell you who is doing weight & balance work/verification. Not exactly a low budget solution, but it should be accurate for weight.
You don't say what geographic area you are in nor the desired field of engineering that you want to pursue.
Is there a professional organization for the area of your interest? Example: If you are interested in HVAC, then join ASHRAE. If you are interested in piping or pressure vessels, then...
You could do it either way control valve or VFD. I would look at a redundant system where you could measure the differential pressure and control the fans speed and then have an additional differential pressure transmitter operation a pneumatic control valve. Look at a Rosemount 3051 with a -3"...
