Question

What is the force acting on a 4 m^2 airplane door if the pressure is 8 psi?Note: 1 psi = 6895 Pascals A) 32 NB) 220,640 NC) 27580 ND) 55160 N

Answer 1

We will have the following:

$F=(8psi\ast\frac{6895Pa}{1psi}\ast\frac{1N/m}{1Pa})(4m^2)\Rightarrow F=220640N$

So, the force is 222 640 N.
