Summer Vacation I have a great summer. At first month I went to summer school for Grade 10 History‚ even though it was super busy but I still having a great time with my teacher and classmates. At the second month‚ my parents decided take me and my younger sister for a driving vacation where headed for Canada’s biggest water park. This water park is locate at Alberta‚ so we decided to travel through all the western Canada. After about 13 days travel in Canada‚ we flew to Miami with another

I’ve lived a long life‚ and along the way I’ve made choices that I’ll never forgive myself for‚ and I don’t expect anyone to forgive me for them either. Some of the most powerful choices I’ve made happened when I was in the war. Where the jungles had such humid air that it was as though I was breathing in buckets of water‚ where danger lurked behind every tree in any form imaginable‚ and where the closest bonds of brotherhood were created. But as I look back on my time in the war‚ there has to be

Abstract The phenomenon of evaporative cooling is a common process in nature‚ whose applications for cooling air are being used since the ancient years. In fact‚ it meets this objective with a low energy consumption‚ being compared to the primary energy consumption of other alternatives for cooling‚ as it is simply based in the phenomenon of reducing the air temperature by evaporating water on it. This process can be an interesting alternative to conventional systems in these applications where

CHAPTER 1 Introduction Some farmers who don’t have irrigation system‚ plant rice during rainy season so‚ they have the difficulty of drying their grains after harvest. Aside from these‚ drying the grains under sunlight takes longer time‚ more effort in handling to the drying site‚ scraping or ricking‚ guarding from animals‚ collecting after drying‚ and another is that the possibility of the grains to be mixed with stones‚ leaves of tree‚ and dust in road drying and field drying. There are many

otherwise be lost in their breath. Air with a high water vapour content leaves the lungs - the unavoidable consequence of exposing a relatively large surface area for the absorption of oxygen. Therefore air which is exhaled has a very high relative humidity - close to 100 per cent saturation‚ and it is also at core body temperature - 38°C. If the temperature of the kangaroo rat’s nasal passage is any cooler than 38°C due to the cooler external environment‚ then water will condense before leaving

moisture is negligible. An experiment showed that the constant drying rate is 4.5 kg/m2-hr and the falling rate begins at 25% moisture. How long is the drying time. What is the % moisture after 1 hour of drying? 3. Hot Air at 90oC and 40% relative humidity is used as heating medium in a tray drier in order to reduce the moisture content of wet sand from 30% to 5%. Weight of dry sand is 5 kg and the tray dimensions are 20 cm by 60 cm by 3 cm. Critical moisture is 15% and equilibrium moisture is 2.5%

Introduction & Theory 2.1 Air Conditioning Air conditioning is a system or process for maintaining a living space or industrial facility at the desired temperature and humidity of the air. The SOLTEQ Air-Conditioning Module can be easily couple to the base condensing unit to form a complete refrigeration circuit. This unit involves several components connected by ducting for the air flow. The unit of air conditioning
