The pressure recorded at your airfield which is at 7000 feet

The pressure recorded at your airfield which is at 7000 feet elevation is 21 in. of mercury. What is the pressure corrected to sea level?

Solution

Lets assume sea level pressure as= P_o

Atmosphereic pressure as = P ( Given As 21 inch of mercury which is equal to = 711.4 hpa )

T is= the temperture ( Lets assume it as 10⁰ C )

Altitude h = 7000 feet = 2133.6 meters

sea level pressure formula = P₀=P(1- (00065h)/(T+0.0065h+273.15))^(-5.257)

putting the values in the above equation and solving by scientific calculator

P₀= 914.71 hpa or 0.9028 atm THIS IS OUR ANSWER.
