: Applications involving Fluid Properties
Instructions: Apply principles of physics such as Newton's law of motion, the conservation of
mass and other laws related to the physical properties of fluids.
- Unless specific values of required fluid properties are given in the statement of the problem,
use standard values.
1. Two engineers wish to estimate the distance across the lake. One pounds two rock together
under water on one side of the lake and the other submerges his head and hears a small sound
0.44 seconds later, as indicated by a very accurate stop watch. What is the distance between
two engineers in feet?
2. A cubical ice block of 24 cm side and of 20 kg weight is allowed to slide down along a glass
plane inclined at 87° to the horizontal on which there is a film of oil having viscosity
2.16x10-3 N ·s/m² .What will be the terminal velocity of the block if the film thickness is
0.025 mm in m/s?
