AI Thread Summary
The discussion focuses on the corrosion of steel pipes transporting salt water and sand, emphasizing the need for empirical equations derived from experimental data. Key factors influencing corrosion include temperature, pH, soluble oxygen, salinity, and the presence of suspended particulates like sand. It is noted that the corrosion rate is likely to increase with higher flow rates, indicating a complex interaction between erosion and corrosion processes. Understanding these dynamics is essential for predicting the longevity and maintenance needs of such infrastructure.

What equations would show the process of corrosion of a steel pipe that is carrying salt water and sand and also would the corrosion rate be different if at different rates of flow?

One would likely need an empirical equation based on experimental data that would include temperature, pH, soluble oxygen, salinity, sand content or suspended particulates.

It would be a complicated erosion-corrosion problem. The corrosion rate should increase with flow rate.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
