- I want to know how much glycerin I can pour into a cylinder so that it doesn't spill when I insert a rod. What is the amount of glycerin adequate to completely cover the cylinder when the rod is inserted? Cylinder measurements outer radius r1 r1 = 4 in inner radius r2 r2 = 3 in outer circumference C1 C1 = 25.132741228718 in inner circumference C2 C2 = 18.849555921539 in height h = 8 in wall thickness t = 1 in Rod measurements radius r = 0.5 in height h = 7 in insertion height ( heights that will be inside the cylinder) h= 5 in volume V = 5.49778714 in3 Glycerin Coefficient of volume expansion β(1/ºC): 500x10^-6 Coefficient of volume expansion β(1/ºC). During inspiration, the volume of the lungs is actively increased by the action of the diaphragm. As the volume of the lungs increases, the pressure within the lungs falls about 1 mmHg below atmospheric pressure. Air rushes into the lungs due to this pressure difference.
