Momentum and CollisionHard
Question
A closed compartment containing gas is is moving with some acceleration in horizontal direction. Neglect effect of gravity. Then, the pressure in the compartment is
Options
A.same everywhere
B.lower in front side
C.lower in rear side
D.lower in upper side
Solution
If a fluid (gas or liquid) is accelerated in positive x-direction, the pressure decreases in positve x-direction. Change in pressure has following differential equation.
where ρ is he density of the fluid. Therefore, pressure is lower in front side.
