What is the total cabin pressure

Reference no: EM13170964

An airplane is pressurized to 650 {rm mm,Hg}, which is the atmospheric pressure at a ski resort at 1.30×104 {rm ft} altitude. If the partial pressure of oxygen drops below 100 {rm mm,Hg}, passengers become drowsy. If this happens, oxygen masks are released. What is the total cabin pressure at which oxygen masks are dropped?
