Answer 2

To calculate the force required to hold back the water pressure at a depth of 1.6 m in a flat-bottomed barge with a hole of 160 cm², we can use the formula for pressure:

Pressure = Force / Area

Given: - Area of the hole (A) = 160 cm² = 0.016 m² - Depth of the water (h) = 1.6 m - Density of water (ρ) = 1000 kg/m³ - Acceleration due to gravity (g) = 9.8 m/s²

We can calculate the force required to hold back the water pressure using the formula:

Force = Pressure × Area

To find the pressure, we can use the formula:

Pressure = Density × Gravity × Depth

Let's calculate the force required:

Calculation:

1. Convert the area of the hole to square meters: - Area (A) = 160 cm² = 0.016 m²

2. Calculate the pressure at a depth of 1.6 m: - Pressure (P) = Density (ρ) × Gravity (g) × Depth (h) - P = 1000 kg/m³ × 9.8 m/s² × 1.6 m

3. Calculate the force required to hold back the water pressure: - Force (F) = Pressure (P) × Area (A) - F = P × A

Let's calculate the force using the given values:

Calculation:

1. Convert the area of the hole to square meters: - Area (A) = 160 cm² = 0.016 m²

2. Calculate the pressure at a depth of 1.6 m: - Pressure (P) = Density (ρ) × Gravity (g) × Depth (h) - P = 1000 kg/m³ × 9.8 m/s² × 1.6 m

3. Calculate the force required to hold back the water pressure: - Force (F) = Pressure (P) × Area (A) - F = P × A

Now, let's plug in the values and calculate the force:
