Give examples why some nail showed corrosion at the air/water interface. An in ground petrol storage tank at an ADNOC station is buried at depth so that sites partially below the water table. Over a period of time where would you expect most external corrosion of the tank? Give reason for your answer Explain the reason for the different amounts of corrosion in the nails in tap water, distilled water and boiled distilled water · » If corrosion of the...
Describe a simple test you will perform to ascertain the corrosion rate of materials? Derive an expression for the corrosion rate of materials. What is the process of aluminium anodising? Plain carbon steel immersed in sea water has a uniform corrosion rate expressed as 0.127 mm per year. The density of iron is 7.87Mg/m2. The atomic weight of Fe is 55.8 g/mol a. Calculate the weight loss per year per unit area b. Calculate the corresponding minimum corrosion current per...
does corrosion increase with high ph or low and why? what is its effect in tubes
In the distillation set-up, what is the purpose of the water-cooled condenser? Sea water is a mixture which has salt, NaCl, dissolved in water. How can these compounds be separated?
Answer both please
Why does fluorenone travel more slowly than fluorene? Why does acetone speed up the rate at which fluorenone travels? (Make sure to include a picture of your TCL plate in your lab report)
Problem 1: The speed of shallow water waves in the ocean (e. g. seismic sea waves or tsunamis) depends only on the still water depth and the acceleration due to gravity. Derive an expression for wave speed.
How does a sea star crawl? If you put a sea star in a vacuum (assuming it would stay alive), could it cling to a rock? Why or why not?
need help #2 and #3
Why is the corrosion of car bodies worse in cities that use salt on the streets in the winter than in cities that do not use salt? Why are copper straps (rather than iron straps or bent over nails) used to hold household copper wire lines in place? When an iron post is immersed in water, rust forms at the water line and the iron post pits below the water line. Explain why this happens....
Why does the speed of sound depend on the temperature in the room? Why does it travel faster if the temperature is hotter?
A 68 kg swimmer does 510 J of work and gets up to a speed of 2.8 m/s from rest. Compute the non-conservative work done on the swimmer by the water.
