The purpose of the flow indicators is, first to insure you have flow to keep the lines flushed, and second to be able to adjust each flow rate so the pressure drop in each sensing line is equal. With equal pressure drops, the dP reading is unaffected by the the pressure drops. There are also...
This is what hardpoints in sandwich structure are for. You can remove the honeycomb around the insert and replace with putty. Or you use rigid plates on one or both sides of the structure so there is little bending moment on the sandwich panel insert.
This one is pretty easy since the one link is vertical. F output is simply the x component of the F input. You can then calculate the resulting torques. But it seems that torque is irrelevant to your problem.
The transverse crack means that the weld is under significant axial stress (circumferential to the pipe). uniform spacing between the cracks is very typical where two materials are bonded together but they shrink or expand differently. The crack relives the stored shrinkage stress of the weld...
That makes perfect sense. But that description sounds a little more complicated than saying to use inductive reactors in series with each scr rather than resistors. Reactors are commonly used to limit AC current where resistive losses are undesirable. My point is that the center tap is not an...
As I recall from reading electronics literature 40 years ago, you will have the same problem with two diodes in parallel. The solution was to place resistors in series with each diode. As little as 0.1 Ohms may be sufficient. It does waste some energy as heat. Perhaps these days there is a more...
Silicone is a condensation cure polymer. It releases methanol or acetic acid during cure. The post cure is intended to complete the cure reaction, which releases these volatile materials. After the reaction is complete it still takes time for volatiles to diffuse to the surface and evaporate...
I don't think that I have ever seen a compressed air distribution system that stayed dry consistently, including instrument air systems. Flow surges are almost impossible to prevent, and driers cannot deal with them. Most humidity sensors are very slow to respond and will not detect transients...
High-vacuum pumps are rated in volumetric flow at actual inlet conditions. They are basically positive displacement pumps that move a constant volume per unit time. Flow stays constant until you get to where the vapor pressure of the lubricant or off-gassing of the materials of the vacuum...
Angular particles are preferred where filtration is the goal. Round particles do reach full compaction much more easily and the flow channels through the bed are more uniform and thus less likely to plug. Any debris that makes it through the front face of the rock bed will more likely make it...
There are differing scales of molecular mobility. In a fluid a molecule can move though it's entire container until it finds something with which to react. All monomers must have at least two reactive sites in order to form and extend polymer chains. Reactive sites on extending chains are...
No one seems to be considering the neutral axis of said beam. As the beam flexes the tension face lengthens and the compression face contracts. The final straight cord length of the tension face must become less than the distance between supports at the trigger point. A thin beam will trigger...
Blue and yellow wires go to run winding.Red and black go to the start winding through the centrifugal switch and capacitors.
To reverse the motor rotation, switch the blue and yellow wires relative to the black and red wires.
Curing is a chemical reaction that stops when all the reactants are consumed, or when the molecules are no longer mobile enough to reach something with which to react. Two part systems are generally very reactive at low temperature, which is why they must be two part. Tg is the glass transition...
The great things about a sand filter are that it will work well in removing fines as well as coarse debris, and backwashing is pretty much fully automated.
It may be beneficial to recirculate water through the filter back into the lake so that the lake water does not become too dirty.
For any given tensile strength and density of a material there is a maximum length of cable/rod that can be self-supported without breaking. Making it a larger diameter will not help in making it longer.
The cross-sectional photos showing the fiber waves was not filament wound. You can see that unidirectional prepreg tape was used because the fiber layers are very uniform thickness with no visible tow structure. ElectroImpact makes fiber placement machines, which can use slit tape. But even...
