A nuclear plant needs to be set up in the outskirts of a big city. The plant needs to be close to the city if the (I^2)R and other logistical losses are to be kept to a minimum, which amount to $1 million per km distance per year. Finally, the plant has a meltdown probability in the next 30 years of 0.02, which, if it happens, can cause loss of life and property in dollar amounts of 3 billion (adjusted for inflation) that linearly decreases with distance from the city and drops to zero at 20 km. If the utility function over money (over 30 years) is exponential with risk tolerance equal to 50 million, determine where the plant should be located if the inflation adjusted profit per year is $20 million.
The cold cranking amperes (CCA) of a conventional lead-acid automobile battery is the amount of current the battery can provide at 0°F for 30 seconds and maintain at least 1.2 volts per cell (or 7.2 volts for a standard 12-volt battery). If a batter..

An air-standard dual cycle has a compression ratio of 18.2 and a cut off ratio of 1.31. The pressure ratio during constant volume heat addition process is 1.5. At the beginning of the compression, P1=80 kPa, T1 = 20°C at the beginning of the cycle. U..
A ?rm has two processes for producing a good, X. Each process uses ?ve chemicals: A, B, C, D, and E. The ?rst process, when operated at unit level, produces 3 tons of X and uses 5, 4, 3, 2, and 1 tons of chemicals A, B, C, D, and E, respectively.
