Like boo1 rightly said,sealants provide the best method of protecting the bolt holes against corrosion.Sealants makes water impermeable to the bolt holes thus preventing water from entering the bolt holes.Sealants can be inform of gaskets etc.Care must be taken while slecting sealants to be used...
Hope you mean porosity in carbon steel and not pourisity because I don’t think any thing like that exist in carbon steel.
If you mean porosity in carbon steel, the following tests can be carried out to determine porosity in carbon steel.
(1) Ultrasonic Testing: a non destructive test that...
I believe injection moulding is used mainly for thermoplastic moulding process.
How It Works
The powder to be used is filled into the hopper of the injection moulding machine.It is then pushed forward by a ram in the machine to the heating cylinder of the injection moulding machine,where...
In continuation,
P= A.Ss
where P is the allowable load you are looking for,A= cross-sectional area of the material and Ss the allowable stress on the material which you must know before you can be able to get P.I believe you can be able to calculate the area and get it on your own.
I believe if you know the maximum amount of stress(internal force) that is to act on the U-shaped bar and also the area of the bar,you can be able to calculate the max. allowable load for the material.
That is since
Ss= P/A where Ss is the max. allowable stress on the material,P=...
Question(1) From what I know about firing of a ceramic body, there is a relationship between fired density and initial particle/grain size of the ceramic body. The initial particle/grain size will determine whether or not the fired density of the ceramic body will...

It is not wise to use dissimilar metals for a design in a high salinity condition(where NaCl is present).Their contact results to galvanic corrosion.In a situation were dissimilar metals are unavoidable(since you are considering your budget),the metal forming the anode should not have small...
Just want to give you the other volumes and air compressor size needed for the volumes.
(A) For (40-60) cfm vol. At 100psi,use (10-15)Hp air compressor.
(b) For (60 –81)cfm vol. At 100psi,use 18Hp air compressor size.
(c) For (81-137)cfm vol. At...
Air compressor sizing depend on the vol. of air which the compressor can disperse(cfm)and the pressure at which the air is being dispersed(psi).Since you have gotten the required vol. for your job,I believe you don't have much problem as regards to compressor size.
1. If your vol. is within the...
