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

Introduction There are many situations in design or in process modelling where it would be useful to know the thermal conductivity of the steel being used‚ and how it would change as a function of temperature. With the lack of any quantitative model the usual recourse is to look for a similar composition contained in published tables of data [1‚ 2‚ 3]. However‚ in the absence of a quantitative model it is not possible to assess the validity of this procedure. Thermal conductivity controls the

1/2 week on each order. The placement of each order is estimated to require 1 hour of clerical time‚ with a direct cost of $15 per hour plus overhead costs of another $5 per hour. A rough estimate has been made that the annual cost of capital tied up in Computronics’ inventory is 15 percent of the value (measured by purchase cost) of the inventory. Other costs associated with storing and protecting the LCDs in inventory amount to 5 cents per LCD per year. (a) What should the order quantity and reorder

The tour operation sectors Tour operators are businesses that merge 2 or more travel services together e.g. accommodation‚ transport‚ tour guide‚ catering and sell them through travel agencies or directly to the consumers as a single product that is called package tour. The package tour might be the combination of services that the consumer wants to get her hand on. Customers chose tour operators rather than organising a holiday independently because it offers a hassle free‚ secure and most of

Our commanders put out orders and make them very clear to us for multiple reasons. One of the main reasons is that these orders are there to protect us as Soldiers and not only our images but the images of our fellow Soldiers and the Army itself. The Army and our commanding officers have our best interests at hand and they put in place the orders they do for that
