Thermodynamics

hi 

I need research paper of 3 pages about any topics in Thermodynamics

 1.Benedictine Orphanage and a new medical building in Tanzania are in need of power supply.  Please design a system which provides power economically and with minimum maintenance.

2.  A region in Honduras needs an economic sanitation system to protect their drinking water reservoir.  Many families do not have electricity yet.

3.  Wright Brothers developed a 100-horse power internal combustion engine for their airplane.  They didn’t have any previous experience to design engines.  Please design a 300 HP.   Please show that an engine with the following specification can provide about 140 HP, as an exercise. 

n  A 6-cylinder I.C. engine with stroke = 9.5 cm, bore = 9 cm

n  Compression ratio=10

n  At intake manifold p=0.8 atm, T=250K

n  Fuel-to-air ratio=0.06 (by mass)

n  h_mech=0.75, h=0.83

n  Running at 3000 rpm

4.  Other Thermodynamic design after consulting with your instructor.  Examples are making ice using solar energy, air-conditioning unit by using camping fire, etc.
