8. a wood chip fueled rankine cycle 54-mw electric power generation plant uses chipped pine bark beatle deadfall as fuel. the overall efficiency of the power plant is 27% and the capacity factor of 80%. the as-received wood fuel is 45% carbon, has a higher heating value of 16.0 mj/kg, and the wood is not harvested sustainably. carbon emissions are taxed at the rate of $25/mgco2e. the life of the system is 25 years and the interest rate is 5.5%. assume an operations and maintenance cost of $0.025/kwh. the initial cost of the system is $4000/kw. the cost of wood chips is $6 per mbtu. a. what is the heat rate of the power plant (btu/kwh)? b. what is the cost of fuel per kwh of electricity generated ($/kwh)? c. how much electrical energy is generated annually by the power plant (mwh/y)?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
