Examination ticket №7

1. Modes of operation of the wind wheel. Characteristicsofwind.

2. Solar radiation. Estimates of solar energy.

3. A farmer has 50 pigs, involves use of manure to produce biogas as a fuel of the car.

A) Discuss the possibility of this. Rate energy possessed by the gas thus obtained and its energy consumption for compression to the desired volume, and compare them with the energy necessary for driving the vehicle into operation..

B) Comment, for any other needs of the farmer may use gasifier.

Please note that 100 kg of pig feces contain about 0.5 kg degradable components in the day and that 1 kg of these components provides a 0,4 of biogas under normal conditions.
