When you use a differential pressure transmitter to measure the height of the fluid inside the tank (where the high pressure side of the DP transmitter is connected to the fluid and the low pressure side is open to the atmosphere), do you have to account for air buoyancy to get the true...
By using the function of the surface parameters, it gives the values of the forces on the faces you chose, and the forces are displayed in x-y-z components. My questions are "Why would the forces be displayed with a negative sign when clearly they should be positive?" "Are the forces negative...
If a object is under a load at a high temperature, how do you include the temperature affect over the tensile and yield strength in the static stress analysis?
The ferrous material is located in a housing that consists other metals. When magnetizing the ferrous material, the housing consitings the ferrous material and other metals is put into the magnetic field produced by the solenoid. The caliberation process is to magnetize the ferrous material to...
Would the mangetic strength of the ferrous material still be stabilzed fairly fast if you magnetize and then de-magnetized with a video tape eraser serveral times?
If you magnetize a ferrous material with solenoid, would the magnetic strength of the material be stablized already right after it being magnetized or would the magnetic strength of the material be fluctuated and then stablized over a period of time?
A centrifugal pump operates at speeds of 200~400Hz, and a flow meter will be installed 10 meters away from this pump. The natural frequency of the flow meter was found to be around 200Hz from SolidWorks Cosmo. The fluid is a high pressure and high temperature water. So how much should the...
If a pump is vibrating with its blade passing frequency in the range of the 200~400Hz and this pump is located 5ft away from a flow meter with its natural frequency around 200Hz, how much higher should the natural frequency of the flow meter be increased to avoid resonance problems?
Even if the first mode natural frequency of the meter can be lowered to 160~170Hz, the second or third mode frequencies will still be around 200~400Hz and coincide with the frequency of the water column pulses.
Even if the meter's natural frequency can be lowerd to 160~170Hz, the frequencies will still be crossed ever time the pumps are turned on. Wouldn't this still damage the meter depending on how long the pumps jump from 160Hz to 200~400Hz range?
Unfortunately, the spectrum is not available. Would it be enough even if the meter's natural frequency can be increased 15% considering the unknown vibration forces caused by the water columns?
Even if the meter is mounted on some isolater stand, would the vibration caused by the water column strokes still destroys the V-cone inside the meter?
A meter will be installed inline in the same pipe between two pumps. The meter is a pressure differential V-cone meter purchased from McCrometer Inc. (www.mccrometer.com). The meter's natural frequency is around 200Hz. The two pump strokes around 200~400Hz, which is considered to cause...
One of our clients wants to purchase a water meter from us. That clients wants to install this meter between two pumps operating at frequency of 200~400Hz. Coincidently, our meter's natural frequency is around 200Hz. Would this cause the meter be destroyed by vibration excited by two...
If a ferrous material is magnetized using a solenoid, would the magnetic strength of the material fluctuate over the next few hours? How long would it take for the magnetic strength of the material be stabilized?
