The length of a diameter of a cylinder in an automobile is the bore.The distance the piston moves in the cylinder is the stroke.The engine capacity or displacement is the combined volume of all its cylinders.To find the displacement of a compressor, find the volume of the cylinder. V = PI*r 2 HTo find the displacement of a compressor with a 2 inch bore and a 3 inch strokeV = PI*r 2 HV = 3.14(1)*2(3) The bore given is a diameter which you need to divide by 2, hence we get 1V= 9.42A positive displacement compressor is the system which compresses the air by the displacement of a mechanical linkage reducing the volume (since the reduction in volume due to a piston in thermodynamics is considered as positive displacement of the piston)Hence, displacement would be 9.42 cubic inches.To know more about Displacement of compressor from the given linkhttps://brainly.com/question/2159231#SPJ4
