Bainite contains needlelike grain structures‚ and it requires an initial rapid cooling followed by gradual cooling.IT is also a micrstrucutre that is another form of steels at certain temperatures from 250-550°C. “Pearlite formation is found from the eutectoid temperature (727°C) down to 400°C. Below 400°C‚ the pearlite microstructure

Study Questions: 1.) Why is sub-soiling needed in soils with hard pans? Sub-soiling is essential especially to hard pan layer because it will help the roots penetrate deep and be able to explore and obtain water and nutrients from larger volume of soil. Hard span obstructs root’s downward proliferation and restricts root growth of crops (of crops that have vertical root growth). With sub-soiling‚ the needed soil depth‚ at least 80cm will be met . With sub-soiling‚ we can break hard pan without

University of Moratuwa‚ Moratuwa‚ Sri Lanka Abstract The purpose of this paper is to demonstrate the adaptability of evaporative cooling technology to Sri Lankan environment. Desiccant cooling technology is initiated to control the relative humidity level of the environment. A generic model of the evaporative cooler is constructed using direct evaporative cooling method and solid desiccant dehumidification method. The model was installed in the testing environment. The results show that the evaporative
