The hydrostatic pressure at a depth of 5 m below the surface of pure water (density 1000 kg/m³) is _______.

Step-by-step solution

1. Write the hydrostatic pressure formula $p=\rho gh$.
2. Substitute $\rho =1000,{\text{kg/m}}^3$, $g=9.81,{\text{m/s}}^2$ and $h=5,\text{m}$.
3. Calculate $p=1000\times 9.81\times 5=49050,\text{Pa}$.
4. Convert to kilopascals: $49050,\text{Pa}=49.05,\text{kPa}$.
5. Round to the nearest whole number: $49,\text{kPa}$.
