Given:
- Velocity of water flowing out of the hole: 5 m/s
- Distance of the flat surface from the hole: 0.1 m
- Acceleration due to gravity: 9.8 m/s^2
- Density of water: 1000 kg/m^3
To find:
Pressure exerted on the flat surface
Formula:
Pressure (P) = Density (ρ) × Acceleration due to gravity (g) × Height (h)
Calculations:
- The height of the water column above the hole can be calculated using the equation of motion: v^2 = u^2 + 2gh, where u is the initial velocity of the water (which can be assumed to be 0) and v is the final velocity (5 m/s).
- Rearranging the equation, h = (v^2)/(2g) = (5^2)/(2 × 9.8) = 1.275 m
Using the formula for pressure:
- P = ρgh = 1000 × 9.8 × 1.275 = 12435 N/m^2 = 12.435 kPa
Answer:
The pressure exerted on the flat surface is closest to 12.435 kPa, which is approximately equal to 12.4 kPa. Therefore, the closest option is (D) 6.8 kPa.
