The following equation gives the number of times the speed of the fluid must change to cause the fluid to flow irregularly. The first number is the number of times for a fluid to go through a loop, or complete an arc, before it flows irregularly. The second number is the number of times the amount of pressure must come to equal one atmosphere. The third number is the number of times for a fluid to flow through two loops before there is a change in pressure from -1 to 1 or from 1 to 2. The fourth number is the number of times for a fluid to flow through three loops before there is a change in pressure from 2. The last number is the number of times for a fluid to flow through four loops before there is a change in pressure from 4. The first number is the velocity at which the fluid is changing its pressure and the second, third and forth numbers indicate the number of times the fluid has to change direction before it comes to a halt in a loop. The Reynolds number is a number used to compare water flow rates between various types of running fluids. For example, if you took a bottle and put your hand into the bottle, the bottles top would probably go into your hand and it would not be able to move around unless your hand was moving. In that case, the bottles top would be very smooth and the bottle would probably not be as slippery as your hand. Water flowing through a loop at a constant velocity, one atmosphere per second, must go through the loop only one time before it reaches the end of the loop and must stop and begin again. If the flow rate is changed from zero to one atmosphere per second, the fluid then has to go through the loop twice and then stop and begin again. If the flow rate is changed from one atmosphere to two atmospheres per second, the fluid then has to go through the loop four times and then stop and begin again. Water is a very viscous substance and it flows unevenly and irregularly in a fluid. Thats why its such a pain to climb stairs; if youre trying to get up a flight of stairs in order to catch a bus, youre going to fall down a flight of stairs because stairs have the potential to be really, really slippery. You try to climb the stairs as quietly as possible. You take your hand out the bottle and let it slide down the side of the bottle, then when you come up to the top, you take your hand and quickly put it around your upper arm and press the bottle against it. You slowly squeeze your hand in a circle, the bottle j.
