Question -
Answer -
Diameter of the first bore,┬аd1┬а= 3.0mm = 3 ├Ч 10тАУ3┬аm
Diameter of the second bore,┬а
= 6.0 mm
Surface tension of water,┬аs┬а= 7.3 ├Ч 10тАУ2┬аNmтАУ1
Angle of contact between the bore surface and water,┬а╬╕=0
Density of water,┬а╧Б┬а=1.0 ├Ч 103┬аkg/mтАУ3
Acceleration due to gravity, g = 9.8 m/s2
Let┬аh1┬аand┬аh2┬аbethe heights to which water rises in the first and second tubes respectively.These heights are given by the relations:
The difference between the levels of water in the two limbs of thetube can be calculated as:
Hence, the difference between levels of water in the two bores is4.97 mm.
