Steam enters a turbine with 8 MPa and 450 \deg C and leaves at 40 kPa as saturated vapour, the mass flow rate is 30000 kg/h. If the power generated by the turbine is 4500 kW, determine (a)What is the heat loss from the turbine? (b) What is the rate of entropy generation for this process, assume the surrounding temperature is 20 \deg C. (c) If there is no heat loss from the turbine, the rate of entropy generation will decrease or increase? Why?

Metropolitan Hospital has estimated its average monthly bed needs as N=1,000+9X where X=timeperiod(months);January2002=0 N=monthlybedneeds Assume that no new hospital additions are expected in the area in the foreseeable future. The following monthly seasonal adjustment factors have been estimated, using data from the past five years: Forecast Metropolitans bed demand for January, April, July, November, and December 2007. If the following actual and forecast values for June bed demands have been recorded, what seasonal adjustment factor would you recommend be used in making future June forecasts?

A firm experienced the demand shown in the following table. *Unkown future value to be forecast Fill in the table by preparing forecasts based on a five-year moving average, a three-year moving average, and exponential smoothing (with a w=0.9 and a w=0.3). Note The exponential smoothing forecasts may be begun by assuming Y t+1=Yt. Using the forecasts from 2005 through 2009, compare the accuracy of each of the forecasting methods based on the RMSE criterion. Which forecast would you have used for 2010? Why?

The economic analysis division of Mapco Enterprises has estimated the demand function for its line of weed trimmers as QD=18,000+0.4N350PM+90Ps where N=numberofnewhomescompletedintheprimarymarketarea PM=priceoftheMapcotrimmerPS=priceofitscompetitorsSurefiretrimmer In 2010, 15,000 new homes are expected to be completed in the primary market area. Mapco plans to charge $50 for its trimmer. The Surefire trimmer is expected to sell for $55. What sales are forecasted for 2010 under these conditions? If its competitor cuts the price of the Surefire trimmer to $50, what effect will this have on Mapcos sales? What effect would a 30 percent reduction in the number of new homes completed have on Mapcos sales (ignore the impact of the price cut of the Surefire trimmer)?
The state of Colorado requires oil and gas companies who use fracking techniques to retune the land to its original condition after the oil and gas extractions. Table 12.9 shows the total cost and total benefits (in dollars) of this policy. Calculate the marginal cost and the marginal benefit at each quantity (acre) of land restored. See Production. Costs and Industry Structure if you need a refresher on how to calculate marginal costs and benefits. If we apply marginal analysis, what is the optimal amount of land to be restored?

HighFlyer Airlines wants to build new airplanes with greatly increased cabin space. This will allow HighFlyer Airlines to give passengers more comfort and sell more tickets at a higher price. However, redesigning the cabin means rethinking many other elements of the airplane as well, like engine and luggage placement, and the most efficient shape of the plane for moving through the air. HighFlyer Airlines has developed a list of possible methods to increase cabin space, along with estimates of how these approaches would affect the planes operating costs and ticket sales. Based on these estimates, Table 13.5 shows the value of R, how much should the firm invest in R on top of the private return; that is, an R private return to HighFlyer Airlines would have a 9 social return. How much investment is socially optimal at the 6 interest rate?
