The most apparent signs and symptoms of a carotid artery blockage include a transient ischemic attack, bruit and a stroke, according to the National Heart, Lung, and Blood Institute.
Measure the length of the cylinder with a measuring tape. Multiply this measurement by the result obtained in the above step. (Example: if the length of your cylinder is 24 inches, then 24 x 113.04 = 2712.96 square inches) Divide the square inch volume of the cylinder by 1728 to get the cubic feet of the cylinder.
Case in point, if you measured a small-block with a cylinder volume of 80 ci at BDC and a cylinder volume of 7.5 ci at TDC, you take those two numbers and divide them you get around 10.6:1 compression. The farther apart these numbers are, the more compression you will have.
