A culture incubator uses a water reservoir to maintain humidity. A pressure sensor is mounted on the reservoir wall at a point 0.25 m0.25\ \text{m} below the water surface. The reservoir is open to the atmosphere. Take water density ρ=1.00×103 kg/m3\rho=1.00\times10^3\ \text{kg/m}^3, g=9.8 m/s2g=9.8\ \text{m/s}^2, and atmospheric pressure Patm=1.01×105 PaP_\text{atm}=1.01\times10^5\ \text{Pa}. Based on hydrostatic pressure, which statement best describes the sensor's absolute pressure reading?
