A vertical cylindrical tank with a diameter of 12m and a depth of 4 m is filled with water to the top with water at 20°C. If the
water is heated to 50°C, how much water will spill over? Unit weight of water at 20°C and 50°C is 9.79 kN/m3 and 9.69
kN/m3, respectively.

What force is required to lift a thin wire ring 6cm in diameter from a water surface at 20°C? (σ of water at 20°C = 0.0728 N/m)
Neglect the weight of the ring.
Solution
P
If we try to lift the thin ring using force P, surface tension inside and outside
of the ring will contract the force. Therefore, we have
P = Finside + Foutside
P = σinsideA + σoutsideA
Since the wire is thin, we can assume that there is no difference
between the inside and outside diameter.
P = 0.0728 (πD) + 0.0728 (πD)
P = 0.0728 (π(0.06)) + 0.0728 (π(0.06))
P = 0.027 N
