Saturated water vapor at 300°F enters a compressor operating at steady state with a mass flow rate of 5 lb/s and is compressed adiabatically to 550 lbf/in.2 If the power input is 2150 hp, determine for the compressor: (a) the percent isentropic compressor efficiency and (b) the rate of entropy production, in hp/°R. Ignore kinetic and potential energy effects.

1. Determine whether each of these production functions has constant, decreasing, or increasing returns to scale: (a) F(K,L)= K^2/L (b) F(K,L)=K+L 2. Which of these production functions have diminishing marginal returns to labor? a) F(K,L)=2K+15L b) F(K,L)=√KL c) F(K,L)=2√K+15√L 3. For any variable X, ΔX = “change in X ”, Δ is the Greek (uppercase) letter delta, Examples: If ΔL = 1 and ΔK = 0, then ΔY = MPL. More generally, if ΔK = 0, then Δ(Y − T...

7. The large tankers that transport oil from the U.S. gulf coast to Canadian refineries typically carry between 800,000 and 1.3 million barrels of product. In order to control the production of refined petroleum, Canadian refineries need to minimize the variation in arrival times of large tankers or their refineries may have too little product on hand. The industry typically views a standard deviation of 9.3 days as acceptable given the influence of weather, labor cost, and mechanical failures cannot...
