Question

9. Water is allowed to flow through a capillary
tube of length 10cm and diameter 2 mm under
a constant pressure difference of 6.5 cm of
water level. If 0.16 litres of water flows in
1 minute, its coefficient of viscosity is,
1) 0.00937 poise2) 0.0937 poise
3) 0.000937 poise 4) 0.937 poise​

Answer 1

Answer:

Water is allowed to flow through a capillary

tube of length 10cm and diameter 2 mm under

a constant pressure difference of 6.5 cm of

water level. If 0.16 litres of water flows in

1 minute, its coefficient of viscosity is,

1) 0.00937 poise2) 0.0937 poise

Explanation:

220 N/m

(2) 110 N/m

(3) 45 N/m

(4) 440 N/mone limb is 3.0 mm and that of the other is 6.00 mm. The tube

is inverted vertically with the open ends below the surface of

water in a beaker. What is the difference between the heights

to which water rises in the two limbs ? Surface tension of

water is 0.07 Nm. Assume that the angle of contact
