MECHANICAL POWER

  • Is available through tractors and oil engines.
  • The efficiency of diesel engine varies between 32 and 38 percent, whereas that of the carburetor engine is in the range of 25 and 32 percent.
  • oil engines of low to medium speed developing about 14 to 20 hp are successfully used for flourmills, oil ghanis, cotton gins, etc.
  • Diesel engines of larger size is used in tractors.

 

Advantages

  • not affected by weather
  • can run at a stretch
  • requires less space
  • cheaper form of power

 

Disadvantages

  • Initial capital investment is high
