Document Summary
Can be static (associated with potential energy) or dynamic (associated with kinetic energy: volumetric flow= volume per time liters/ min; m^3/ sec. Work and power: consider the following 2 systems, a. 10 liters pumped out in 10 minutes: b. 11 liters pumped out in 40 minutes: which system performed more work, which system has more power, a: 10l/ 10 min= 1l/min, b: 11l/ 40min= . 284 l/min, a has more power. Relating power, work, and energy: a 50 watt light bulb is run for 100 hours. Energy gradient: why does blood move from one location to another, higher energy to lower energy, or across a pressure gradient, energy is given to blood from the heart during systole. Flow conversion between potential and kinetic energy: assuming no loss of energy to heat, as the flow accelerates, there is a decrease in potential energy and a compensatory increase in kinetic energy (transitioning from region 1 to region.
