Pregunta:
What is the Atmospheric pressure at sea level & at the Cruising altitude of a passenger plane (why must aircrafts be pressurised?)
Autor: Miqdaam Hamed HassanRespuesta:
At sea level: 101,000 Pa (101 kPa) Cruising altitude of a passenger plane: 27,000 Pa (27 kPa) ∴ air crafts must be pressurised as humans cannot take in oxygen quickly enough to meet their bodies’ needs
