First the total volume of gas that is to be stored needs to be calculated. From the mass balance it is known that 30.92 kmol of methane can be expected every hour. This correlates to 742.0 kmol/day. The ideal gas law will be used‚ with a compressibility factor‚ Z‚ to account for departure for un-idealality. An operating temperature of 50 will be assumed‚ as this is the highest feasible ambient temperature that can be expected. Also assume that the pump or compressor used to transport the methane

1. In general‚ why have many different alloys been developed and used? Many different alloys have been developed and used due to the various properties they have when alloyed which increase their amount of uses. Properties such as increased tensile strength‚ the variation in melting point‚ malleability and luster are all properties that come as a result from alloyed metals. For example‚ carbon and manganese form an alloy called carbon steel‚ which is very hard and can therefore be used to make things

is about 18% in Europe‚ 8% in America and 3% in Asia. These percentages decrease significantly with increasing part complexity [1‚ 2]. These applications require alloys having properties like a high strength to weight ratio‚ dent resistance‚ corrosion resistance and good formability [3]. Apart from material and manufacturing cost‚ the poorer formability of aluminium alloys compared to that of steels is one of the most important reasons for the relatively low market penetration of aluminium

Examination revealed 60% of the panel had been damaged by corrosion. The damage was most severe at the point of rupture. As a result of the occurrence the manufacturer issued out an inspection of the area on the entire 1124 westwind fleet. ATSB findings concluded that the environment and lack of fuselage inspection

stress on it. Obviously‚ this will cause a negative lasting impact on car battery life. Clean the battery terminals- When it comes to battery life‚ corrosion is prime concern. Steady corrosion will affect battery’s performance. It will simply drive it closer to death. When harmful stuff builds up around the battery terminals‚ it will cause corrosion. Battery terminals are made up of lead. Therefore‚ they are more likely to damage if not properly maintained. You should be keen towards cleaning these

Gao School of Mechanical Engineering‚ Beijing Institute of Petrochemical Technology‚ Beijing 102617‚ China Abstract Stress corrosion cracking is the major threat to the safe and stable operation of nuclear power plants‚ and the residual tensile stress is one of its major causes. For in-service nuclear power plants‚ the most effective means to prevent stress corrosion cracking is change the stress status of material surface by peening technology.
