energy lost during the compression of the fluid between state 1 and state 2. To be able to calculate the cost of operating the refrigeration cycle using these fluid‚ we first need to calculate the compressor work using equation 10. The larger the compressor work is‚ the more electricity the compressor is drawing. We can multiply the number of kilowatts to the number of hours electricity will be used in a month to calculate the number of kilowatt hours‚ i.e. 720 hours assuming a 30 day month. Using

| Distillation is defined as: `Distillation is based on the fact that the vapor of a boiling mixture will be richer in the components that have lower boiling points.Therefore‚ when this vapor is cooled and condensed‚ the condensate will contain more volatile components. At the same time‚ the original mixture will contain more of the less volatile material. Distillation columns are designed to achieve this separation efficiently.Although many people have a fair idea what “distillation” means‚ the

REFRIGERATION CYCLES Carnot Cycle We start discussing the well-known Carnot cycle in its refrigeration mode. Figure 1: Carnot Cycle In this cycle we define the coefficient of performance as follows: COP = qL TL = w TH − TL (1) Which comes from the fact that w = qH − qL (first law) and qL = TL Δs ‚ qH = TH Δs (second law). Note that w is also given by the area of the rectangle. Temperature differences make the COP vary. For example‚ the next figure shows how COP varies with

2. Justify your allocation based on your outlook for systematic risk in the U.S. Systematic risk is primarily based on the risks that are associated with actual or real events that may affect the market. This includes interest rates‚ inflation‚ wars and all that can affect the market and cannot be avoided through diversification. Systematic risk can be associated with riskier securities if and when compared to bonds. This rate of return is mainly unpredictable but can be profitable. My reasoning

Research on gas masks I researched gas masks. I found out about: The history Gas masks were issued to all British civilians at the start of World War 2. In Britain fear was around because the British government thought that the Nazi German bombers would drop poison gas bombs. At the start of the war some citizens had not been issued with a gas mask. In a government document "If war should come" the explanation for this was that district leaders might have decided to keep gas masks in storage
