Ⅰ. INTRODUCTION
Ⅰ. LED
LED(Light Emitting Diode)는 반도체에 전압을 인가할 때 생기는 발광현상을 이용한 광원이다. 전기를 통해주면 전자가 에너지 레벨이 높은 곳에서 낮은 곳으로 이동하면서 특정한 파장의 빛을 내는 화합물 반도체에
Calculations of the design of each unit operations
Flowrate
Present Average Flowrate = 4220 m3/d
Water use per capita = 4220/15000 = 0.281333 m3/d capita
Population after 10 years = 15000 Χ 1.0310 = 20158.75 ≒ 21000 capita
∴ Average Flowrate = 0.281333 Χ 21000 = 5908 m3/d ≅6000m3/d
Peak Flowrate = 5908 Χ 1.5 = 8862 m3/d ≅9000 m3/d

We design the research in a way that the requisite data can be gathered and analyzed to arrive at solution. We will follow the six basic aspects to design our research. They are the purpose of the study, the types of investigation, the extent of researcher interference, the study setting, the unit of analysis, the time horizon of the study.
Purpose of the study: Hypotheses testing
