Greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases and is re-radiated in all directions. Since part of this re-radiation is back towards the surface‚ energy is transferred to the surface and the lower atmosphere. As a result‚ the temperature there is higher than it would be if direct heating by solar radiation were the only warming mechanism. Solar radiation at the high frequencies of visible light passes through the atmosphere

is -10oC. Take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h1 = 10 W/m2.oC and h2 = 40 W/m2.oC‚ which includes the effects of radiation. 3.A steam at T∞1=320oC flows in a cast iron pipe (k=80 W/m.K) whose inner and outer diameters are D1=5 cm and D2=5.5 cm‚ respectively. The pipe is covered with 3-cm thick glass wool insulation with k=0.05 W/m.K. Heat is lost to the surroundings at T∞2=5oC by natural convection and radiation‚ with a combined heat

Understand how homeostatic mechanisms operate in the maintenance of an internal environment Homeostasis is keeping the body balanced to allow cells to function‚ despite external environment. Homeostasis is important because the cells‚ blood and tissue fluids can change by slowing down or even stop a vital chemical reaction. Its aim is to keep the body to stay the same‚ at a normal condition. Negative feedback is when change is detected; there are steps when change is detected to get it back

The synthesis of this is an always individualised ‘inhabitable wrapping’.Nature provides us with climatic conditions (variation in air temperature‚ incident solar radiation‚ wind systems‚ air direction‚ speed and humidity)‚ which can be passively harnessed through purely architectonic devices.The essential principle of bioclimatism is that of building with the climate.

D type boiler design: SZS series of boiler are design by double drum‚ longitudinal type‚ full water pipe structure. It is consist of the upper and lower drum‚ convection bank and the left and right set of boxes. The total size are close-knit‚ and the external appearance is elegant and beautiful. It apply to com-bust under slightly negative pressure because the water screen of the boiler furnace is use of close-packed
