Chapter 6, Problem 6.2DOEP

Why is humans are very dependent on the used of fuels to produce power?

Determine the uses of diesel and gasoline engine in agriculture

The larger the specific volume, the greater the work produced (or consumed) by a steady-flow device.

1. Who has invented the first internal combustion engine vehicle? when?

Prepare an engine heat balance and distribution of energy table for the following test data gathered from a Diesel engine plant. A diesel engine plant was tested for one hour in the course of a feasibility study. The following data were gathered in the course of the test. a. Duration of the test One hour b. Generated power 600 kW c. Fuel consumption 18.2 kg at 27 degrees Celsius d. Specific Gravity of fuel 0.930 e. Cooling water flow 950 liters/minute f. Inlet & outlet temperature of cooling water 32 degrees & 45 degrees Celsius respectively 25:1 g. Air-fuel ratio h. Ambient temperature 32 degrees Celsius i. Exhaust gas temperature 425 degrees Celsius j. Specific heat of exhaust gas 1.07 kJ/kg K k. Manufacturers data Generator capacity 650 kW Generator efficiency 92 %

As a patent attorney you are asked to verify if a certain patent application should be approved, which means whatever is being patented must be possible/practical to build and work. The patent presents a new power plant designed to use a fuel capable of achieving a maximum temperature of 550 degrees F. The fluid flowing in the power plant system is to be cooled by a lake with temperature equal to 85 degrees F. The patent application indicates the power plant to be capable of achieving 0.78 thermal efficiency. Should this patent application be approved based on the information available? Why?

Create an introduction about impacts of Biofuels production from various crops.

4. The discussion of electricity costs in section 8.6 stated that coal costs of $1.00 - $1.50 per million BTU are equivalent to about $24-$36 per ton, and that natural gas costs of $2.00 - $5.00 per million BTU correspond, on an equivalent energy basis, to $12-$30 per barrel of oil. Use the data on fuel properties in table 8.1 to confirm these equivalencies.
