1

An object with mass $10\textup{ kg}$ and volume $4\textup{ L}$ and reference area of $0.05\textup{ m}^2$ is sinking in water with a constant velocity of $2\ \frac{\textup{m}}{\textup{s}}$ . What is the drag coefficient of the object?

$g=10\ \frac{\textup{m}}{\textup{s}^2}$

$\rho_w = 1000\ \frac{\textup{kg}}{\textup{m}^3}$

2

Viscosity is defined loosely as internal friction in a fluid. Which of the following fluids would you expect to have the highest viscosity?

3

A spherical ball of mass and radius is sinking in water. What is the terminal velocity of the ball?

$g=10\frac{m}{s^2}$

$\rho_w = 1000\frac{kg}{m^3}$

$C_{D_{sphere}} = 0.47$
