Calculation of the Surface tension(γ) of liquid
Assume that cosΘ ~ 0.9 (Contact angle : 22.5º ~ 30º)
Thus, γcosΘ value can give the information about Approximate value of Surface tension(γ)
γcosΘ value for the given liquids are computed
Assumption and Condition of experiment
Room temperature : 20ºC
Density of Glycerol : 1261kg/m3
Contact angle of Glyc
Chest tubes are routinely used to drain blood and other matter from the chest cavity after heart and lung surgery
Clogging of the chest tube can contribute to retained hemothorax, pleural effusion, empyema, pneumothorax, and subcutaneous emphysema
Clinicians often employ large-diameter tubes, however, such large-diameter tubes are associated with increased pain

Strength of matrix MMC : Boron fiber/Al (2024) alloy
300M :
Raw material of the MMC
- Boron cost : 5000$/Kg
- Al (2024) alloy : 6000 won/Kg
300M(AMS 6417) : 168$
Produced in single-filament reactors by CVD, boron fiber exhibits a unique combination of High Strength High Modulus and Large Diameter.
Elemental boron is deposited on a fine

GENERAL GREY
Looks like a big turd.
The two Officers exchange a glance.
COMMANDING OFFICER
We estimate it has a diameter of
over five hundred and fifty
kilometers and a mass roughly one
fourth the size of our moon.
The General turns to the Second Officer, concerned.
GENERAL GREY
A meteor?
SECOND OFFICER
No Sir. Definitely not.

• Sputtering?
Sputtering is a process whereby atoms are ejected from a solid target material due to bombardment of the target by energetic particles.
Advantage
Sputtering of insulating film
Homogeneities of film thickness
useable for large target
