Blood (assume u 4.5 x 105 lb.s/ft? , sg =1.0) flows through to its head at a rate of 2.5 x 104 ft/s. assume the artery length is 10 ft and the artery diameter is 0.20 in. if the pressure at the beginning of the artery (outlet of the heart) is equivalent to 0.70 ft hg (phg 26.3 slug/ft'), determine the pressure at the end of the artery when the head is 8 ft above the heart. an artery in the neck of a giraffe from its heart

All particles have energy, and the energy varies depending on the temperature the sample of matter is in, which determines if the substance is a solid, liquid, or gas. Solid particles have the least amount of energy, and gas particles have the greatest amount of energy.The temperature of a substance is a measure of the average kinetic energy of the particles. A change in phase may occur when the energy of the particles is changed.There are spaces between particles of matter. The average amount of empty space between molecules gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases.
