Hello,
I'm trying to calculate the bulk material flow (kg/sec.) in a pipe (15.75" ID, gravity feed). The material is coal. Does anybody know of any resources that discuss this topic or derives the equations? Particle size would be >500 mircon, bulk density of ~800kg/m^3.
Thanks in advance,
Ed
Hello,
I have just completed some modifications to the exterior of my home and now have to backfill. The area that requires backfill is about 10x14x4', the existing fill around the house appears to be clay. What is the appropriate backfill? Is it better to use sand or gravel?
thanks,
Ed
Hello,
I'm trying to setup a simple model of a rectangular bolted flange that is under uniform pressure on one side. I wish to examine the resulting displacement of the flange when a bolt is removed under pressure (i.e. will gas escape in this region). The flange is big 10' x 6' x 2" thick...
Hello,
I was wondering if anyone has any information regarding back gouging and when it is required. We have just welded a 3" plate with a backing strip (bevel prep.), removed the backing strip and now are wondering if the side that the backing strip was on should be back gouged and welded...
Hello,
How do you calculate bolt stiffness using VDI2230 method?
Is:
Kb=KtKd/(Kt+Kd)
A valid formula to calculate the stiffness in the bolt?
Where:
Kt=AtE/lt
Kd=AdE/ld
At=tensile-stress area
Ad=major-diameter area of fastener
lt=length of threaded portion of grip
ld=length of unthreaded...
Hello,
I'm trying to constrain a coil inside a hollow tube. Presently I'm using a mating and angle constrain but I still can freely move the coil part away from the tube. What technique should I use to properly constrain it? The insert constrain does not work for the coil. I am rather new...
Hi,
I'm trying to do an energy balance on a process. I'm using water to cool a heated object (~1000C). Once the water contacts the surface steam is produced. This steam passes through the object and cools it. Is there an equation for this type of evaporation?
Thanks,
Ed
No,
I have not unchecked the photoworks in Tools\addin
I deleted the data subdirectories inside the Solidworks directory for photoworks (I know really stupid mistake). I believe the program is trying locate a certain folder but can't find it. Does anyone have the folder names for the...
Hi,
I was removing folders in my computer haphazardly and deleted the photoworks data directory. Everytime I startup solidworks I get an error referring to solidworks not being able to find the scenes and image directory for photoworks. I don’t really use it, do I need to reinstall the...
