such as red cod‚ spotty and kahawai challenge them. There are predators such as dolphins‚ sharks and also people. Their gas exchange system has to be efficient for them to be able to compete with those fish and escape from predators. Fish live in an acquatic environment. Water contains a less % 02 than the air so fish mush have a very efficient gas exchange system. This has prompted the development of the gill system. Air has 20% 02‚ water has much less. The gills are supported by the gill arch

Solar Panels- They make electricity so you don’t have to buy it. You don’t have to use coal/oil/something else to create electricity‚ so it saves fossil fuels also. Tankless Hot Water Heater- Heating water is the 2nd highest energy use in the home. This device saves energy by eliminating the storage tank for hot water that has to be constantly heated. You only heat the water you use. Florescent Light Bulbs- These use less electricity than an incandescent bulb for the same amount of light

Efficient Propeller Design | AbstractHow does a helicopter generate enough lift to fly? How does a speedboat get moving fast enough to pull someone on water skis? Here ’s a project on designing propellers to do the job. ObjectiveThe goal of this project is to investigate how changes in chord length affect the efficiency of propellers.IntroductionA propeller‚ like an airplane wing‚ is an airfoil: a curved surface that can generate lift when air moves over it. When air moves over the surface of

Shading: Shadow Angles When attempting to shade a window‚ the absolute azimuth and altitude of the Sun are not as important as the horizontal and vertical shadow angles relative to the window plane. These can be calculated for any time if the azimuth and altitude of the Sun are known. Horizontal Shadow Angle (HSA) This is the horizontal angle between the normal of the window pane or the wall surface and the current Sun azimuth. The normal to a surface is basically the direction that surface
