-Analysis
Our team made up strategic management theory which S.W.O.T and Porter's five forces model about LVMH.
First of all, we can recognize the opportunities and threats that LVMH can have, by external analysis
*Opportunities
-more chances for international market
-branding with culture and art
-synergy effect from trendsetters
-wide range of customer
*Threats
-excessive competit
Inertia force is high
The mean velocity is fast
The flow rate is more than laminar flow
Small disturbances produce eddies

4) Close valve#8 and give the pressure by blocking ‘vinyl’ pipe by using valve V4, V5, V9.
Remove the air in pipe by open and close valve V4, V5, V9.
Then, control valve #3 V3 to flow more than 100L/hr.
- If water doesn’t flow at all, follow these operations again and again.
Evaluate the pressure drop driven by each pipe accessories such as
Gate valve, Standard Elbow Bend,
90˚ Mitre Bend, Straight pipe, Glove Valve and Sudden Enlargement.
Q = V1A1 = V2A2
The Law of Conservation of Mass states that mass can be neither created nor destroyed.
Using the Mass Conservation Law on a steady flow process through a control volume where the stored mass in the control
Objective
Distillation is an important process in both chemistry and industry. Distillation probably accounts for 90% of all separation processes in the chemical industry.
In this experiment,
We will understand the principle of distillation and separate a mixture of two miscible liquids(liquids that mix in all proportions) with different boiling points.

5. 실험방법
① Reynolds Number 측정장치에 물을 공급하여 만수가 되게 하고 나머지 물은 over-flow 시킨다. 그런 후 수위를 일정하게 유지시킨다.
- 수조안에 있는 벨마우스 이상으로 충분하게 물을 채운다.
- 수돗물이 수조로 들어가는 만큼 배수되게 한다.

turbulent 소요동력 식 :
P = power requirement (W)
D = diameter of impeller (m)
k = constant
n = rps (sec-1)
