The pressure inside a piston cylinder is a variable of

Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)

Radius

Plane angle

Z plane distance

Constant, not a variable

Correct Answer : Option (C) : Z plane distance

Explanation : Pressure varies up and down in a cylinder due to suction. Thus it is dependent on the z plane distance of the cylinder.
