Q:I had a physics exams today and it was asking whether or not a shiny surface aluminium blanket was suitable to keep the sleeper warm. I put that because it's a conductor of electricitiy, heat loss will be greater so it wont be suitable for keeping him warm. On the other hand, some other people said that because it had a shiny surface, thus a good reflector of heat, it would be suitable for keeping him warm. Are both arguments correct?

Metals are reflective for the comparable reason that they habit electrical energy. The steel has an excellent number of electrons that are very loosely guaranteed to the atoms; they are in a position to leap from one atom to a distinctive very quite. that's virtually like a sea of electrons. Electrons soak up photons of sunshine then re-emit them in random instructions, that's stated as scattering. you are able to think of that if the electrons emit the photons in random instructions then the floor could be boring white, no longer vivid, yet in reality so long as a results of fact the floor irregularities on the steel are smaller than a wavelength of sunshine each and all of the photons entering into extraordinary instructions cancel one yet another out, in simple terms leaving those that leap off on the comparable attitude they arrived at - mirrored photograph in different words. Metals are literally sparkling. you are able to locate that frustrating to have self belief yet once you're finding at an liquid crystal reveal reveal screen you're finding by using a layer of steel now - it varieties electric powered circuits on the returned of the glass reveal. Any cloth that reflects easy additionally transmits it. while the electrons are greater efficient at interacting with the photons of sunshine the fabric is greater reflective, as in a steel; while fewer electrons are interacting with the easy the fabric is greater transmissive, like glass or water. yet observe that cup and water the two mirror easy besides as transmit it.

This texture provides a rustic, handcrafted look, making it suitable for applications such as decorative accents, light fixtures, and furniture. 6. Perforated: Perforated texture involves creating a pattern of small holes or perforations on the surface of the aluminum coil. This texture allows for increased airflow, light transmission, and sound absorption, making it commonly used in applications such as ventilation systems, acoustic panels, and decorative screens. These are just a few examples of the various surface textures available for aluminum coils. The choice of texture depends on the specific requirements of the application, including aesthetics, functionality, and durability.

Q:How are aluminum coils used in the production of heat exchangers?

Aluminum coils play a crucial role in the production of heat exchangers. Heat exchangers are devices used to transfer heat between two or more fluids, allowing for efficient heating or cooling in various applications. The use of aluminum coils in heat exchanger production is primarily due to the unique properties of aluminum. Firstly, aluminum is an excellent conductor of heat. It possesses a high thermal conductivity, which means it can efficiently transfer heat from one fluid to another. This property is particularly important in heat exchangers, as it ensures that the heat exchange process is rapid and efficient. Secondly, aluminum is lightweight and has a high strength-to-weight ratio. This makes it an ideal choice for heat exchangers, as it allows for the production of compact and lightweight units that can be easily installed in various systems. The lightweight nature of aluminum coils also reduces the overall weight of the heat exchanger, which can be advantageous in applications where weight is a concern, such as automotive or aerospace industries. Additionally, aluminum coils have excellent corrosion resistance. Aluminum naturally forms a thin oxide layer on its surface, which protects it from corrosion.

Q:A cube of solid aluminum has a volume of 1.00 m3 at 20°C. What temperature change is required to produce a 130 cm3 increase in the volume of the cube?

The linear expansivity of aluminum is 23 x10^-6 /K. Bulk expansivity is 3 x 23 x10^-6 / k For 130 [cm^3] the temperature required is 130 [cm] ^3/ 3 x 23 x10^-6 = 0.00013/[3 x 23 x10^-6] = 1.88 K ========================= If each side of the cube of side 1m expands by e, then its new volume = [1+e]^3 = 1 + 3e + 3e^2 +e^3. Neglecting high powers of e as negligible, the increase in volume is 3e. But e = 23 x10^-6 x rise in temperature 3e = 3*23 x10^-6 x rise in temperature. Given 3e = 0.00013 0.00013= 3*23 x10^-6 x rise in temperature Rise in temperature = 0.00013 / 3*23 x10^-6 = 1.88 K
