A man blows into one end of a U-tube containing water until the levels differ by 40.0 cm. if the atmospheric pressure is 1.01 × 105 N/m² and the density of water is 1000 kg/m³, calculate his lung pressure.

---

Lung pressure = atmospheric Pressure + liquid pressure
P1 = P0 + hpg. Hence P1 = (1.01 × 105) + (0.4 × 10 × 1000) = 1.05 × 105 N/m²
