What is the displacement of the barge in tonnes? Use the block coefficient and dimensions provided.

Step 1: Answer Question 1f.
To calculate the displacement of the barge, we use the formula:

$$\Delta = V \times \rho$$

where $\Delta$ is the displacement, $V$ is the volume of displacement, and $\rho$ is the density of water.
The volume of displacement can be found using the block coefficient ($C_b$) and the overall dimensions of the barge:

$$V = C_b \times L \times B \times T$$

From the given orthographic views in Figure 1:

• The overall length ($L$) is 8 cm (from the side view).
• The maximum breadth ($B$) is 6 cm (from the top view and front view).
