Question
An aeroplane of mass 3 × 104 kg and total wing area of 120 m2 is in a level flight at some height. The difference in pressure between the upper and lower surface of its wings in kilo pascal is (g = 10m/s2) : -
Options
A.0.2
B.5.0
C.10.0
D.12.5
Solution
Force due to pressure difference = ᐃP × A
In balanced condition
= mg = ᐃP × A
= 2.5 kPa
In balanced condition
= mg = ᐃP × A
= 2.5 kPaCreate a free account to view solution
