Exercise 4

The specific weight of a certain liquid is 1366 kg/m3.

Determine its density and specific gravity

Exercise 6

A liquid has a specific weight of 945 N/m3 and a dynamic

viscosity of 131.67 N s/m2. Determine its kinematic viscosity.



8/9

Exercise 7

A piston having a diameter of 13.92 cm and length of 24.13

cm slides downward with a velocity of V through verticalpipe. The downward motion is resisted by an oil film between

the piston and the pipe wall. The film thickness is 0.05 cm

and the cylinder weigh 0.23 kg. Estimate the V if the oil

viscosity is 0.766 Pa s. Assume the velocity distribution inthe gap is linear.

Exercise 8

Estimate the increase in pressure (in kPa) required to

decrease the unit volume of mercury by 0.1 %.
