discussion of aerodynamics. The lines in Figure 3.1 which indicate how the air flows are known as streamlines. Each streamline is drawn so that at every point along its length‚ the local velocity vector is tangent to it. A tube composed of streamlines is called a stream tube. In a steady flow‚ each streamline will also be the path taken by some particle of air as it moves through the flowfield (a region of air flow). A steady flow is defined as one in which the flow properties (pressure‚ temperature

sunlight and scanned the water in front of me. With my teeth clenched on my whistle‚ I paced the hot concrete. All of a sudden‚ the slide screeched as an older woman plunged into the pool. I instinctively moved towards the struggling guest with my safety tube outstretched‚ ready to execute my training. Suddenly‚ she emerged from the water and exited the pool. Whew! It was a false alarm. While heading back to my stand‚ I was interrupted by the creaking of another slide. This time the water seemed to be moving

Activity 1.3.1: DNA Detectives Introduction Bones can provide a snapshot of the identity of a person- they can predict height‚ stature‚ gender‚ ethnicity and even age. However‚ it is what lies inside these hard calcified tissues‚ the DNA housed inside the body’s cells‚ that holds the key to true genetic identity. Tissue is made up of many cells‚ the building blocks of life. Tucked inside the body’s cells‚ you will find chromosomes. These structures house your genes and contain the DNA code necessary

also allows the engineer to put the train into reverse.)\ You can see in this diagram that the exhaust steam simply vents out into the air. This fact explains two things about steam locomotives: It explains why they have to take on water at the station -- the water is constantly being lost through the steam exhaust. It explains where the "chow-chow" sound comes from. When the valve opens the cylinder to release its steam exhaust‚ the steam escapes under a great deal of pressure and makes a "chow
