AIRCONDITIONING PSYCHROMETRICS AIR CONDITIONING PSYCHROMETRICS In air-conditioning system‚ the air must undergo one or several of the following processes: Psychrometrics can be used to predict changes in the environment when the amount of heat and/or moisture in the air changes. Use of psychrometric analysis is also important to determine the volume flow rates of air to be pushed into the ducting system and the sizing of the major system components.

boiling and melting point of all alkaline metals. Its density is 1.74g/cm^3 and at room temperature (20°C) it is a solid. Magnesium is protected by a thin layer of oxide that is difficult to remove and is impermeable. It’s heat of fusion is 8.48 kJ/mole‚ and it’s heat of vaporization is 128 kJ/mol. The only way for magnesium to naturally occur is

they perform best when the heat source can supply heat at a high temperature with little temperature drop. Absorption refrigeration systems involve the absorption of a refrigerant by a transport medium. The most widely used absorption refrigeration system is the ammonia–water system‚ where ammonia (NH3) serves as the refrigerant and water (H2O) as the transport medium. Absorption refrigeration systems are economically attractive when there is a source of inexpensive heat energy at a temperature of

distilling a solution. Thesolution of 50/50 ethanol-water was used in the experiment. Using fractional distillationapparatus ethanol-water mixture was separated. The fractional use of copper sponge wasused in distillation process which created the heat exchange area between the vapor of ethanol and liquid water. The fractional distillation process yield 9.5 ml of ethanol incollecting flask‚ thus the hypothesis was accepted.The purpose of this experiment is to understand the process of distilling

It is very interesting to know about the process in detail as it is a natural process. The story begins when a liquid or solid state of mater responds to the heat in environment. The heat makes the liquid state or solid state of matter to convert into gas state. Liquid Gas (Vaporization) Solids Vapor state (Sublimation) This can be observed in the process of evaporation that clouds are made of pure distilled

Analysis: 1. Explain why blood pressure and heart rate differ when measured in a reclining position and in a standing position. When a person stands‚ the heart must pump blood against the pull of gravity to reach important areas such as your brain. Veins must work hard to get blood back to your heart. As a person reclines‚ the heart does not have to pump as hard to reach the same areas‚ decreasing the blood pressure. Also‚ a person is usually more relaxed in a reclining position‚ which

contribute to the efficiency of distillation‚ the first‚ most obvious is the boiling points of the compounds themselves. If one compound is significantly more volatile than another (∆bp > 40 C)‚ then the compounds can be effectively separated in one vaporization step‚ in a process called simple distillation. However‚ if the boiling points of the compounds are too similar‚ then the vapor produced at any given temperature will be a mixture of the two compounds. This time‚ a process called fractional distillation
