1. In ammunition testing center the pressure is found to be 255 MPa. Calculate the change
in volume of the piece of the copper piece when subjected to this pressure in
percentage. The bulk modulus of copper is 1.38 x Pa.
2. Two liters of water, when subjected to a pressure of 10 atm, are compressed by 1.013
cc. Find the compressibility of the water. Note: Compressibility = 1/K.
3. A solid rubber ball has its volume reduced by 14.5% when subjected to uniform stress of
1.45 x 10 4 N/m 2 . Find the bulk modulus for rubber.
4. The capillary rise when a glass capillary tube of diameter 0.4mm is dipped vertically in
olive oil is 3.8mm. If the angle of contact of olive oil with glass is 0 deg and the density of
olive oil is 920 kg/cu.m, find the surface tension of olive oil.
5. A liquid rises to a height of 9cm in a glass capillary of radius 0.02 cm. What will be the
height of the liquid column in a similar glass capillary of radius 0.03 cm?
