A vessel immersed in fresh water to the waterline displaces 15,000 m3 of water.

A vessel immersed in fresh water to the waterline displaces 15,000 m3 of water. The weight of the vessel without cargo is 5 • 10 ^ 6 N. What is the weight of the cargo.

To find the weight of the cargo that was loaded onto the vessel in use, we use the formula: Pg = P – Pc = ρw * g * V – Pc.

Values of variables and constants: ρw – fresh water density (ρw = 1000 kg / m3); g – acceleration due to gravity (g ≈ 10 m / s2); V is the volume of displaced fresh water (V = 15000 m3); Рс – own weight of the vessel (Рс = 5 * 10 ^ 6 N).

Let’s perform the calculation: Pg = ρw * g * V – Pc = 1000 * 10 * 15000 – 5 * 10 ^ 6 = 145 * 10 ^ 6 H = 145 MN.

Answer: The required weight of the cargo on the vessel in use is 145 MN.
