Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Problem 4: Heart Mechanics The human heart is a pump. Assume an average person with 5.3 L of blood, which has a specific gravity of 1.060 and a dynamic viscosity 3 times that of water. Assume a temperature of 35°C, a resting pulse of 90 beats/minute, heart discharge of 5.0 L/min, and head change of 35 mm Hg. By the way, that head change corresponds to a blood pressure of "105-over-70", which means the high pressure is 105 mm Hg, and the low pressure is 70 mm Hg, giving AH = 35 mm Hg. Part A What is the power delivered to the blood by the heart? [W] Part B If the power required by the heart is 2.0 W, what is the heart's efficiency? [-] Part C What is the heart's daily energy requirement? [kJ] Part D Convert the units from [kJ] to [number of milk shakes]. 4.2 kJ = 1 food calorie, and assume a 16 oz Strawberry Triple Thick Shake containing 560 food calories.
