Abstract
The activities on the field practice program were agricultural and biosystems-related activities conducted at CLSU Ceneter for Renewable Energy and Technology (CREaTe). the field practices was focused on four activities which were the performance evaluation of different sizes 3" and 4" centrifugal pumps as hydro turbine, assistance in design, fabrication and performance evaluation of biomass shredder, assistance in performance evaluation of water wheel using DC generator and assistance in design, fabrication and performance evaluation of hydro vortex turbine.
For activity 1, the student evaluated different sizes of centrifugal pump as a hydro turbine. The calculated hydraulic efficiency of the 3" centrifugal pump as a hydro turbine was 83.32% with the total power efficiency determined to be 86.2% then the hydraulic efficiency of the 4" centrifugal pump was 93.71% with a total power efficiency of 91%.
For activity 2, the student assisted on the testing of the biomass shredder to determine the performance of the machine based on PAES criteria for biomass shredder in terms of shredding efficiency. It was found that the biomass shredder satisfied the minimum requirement of 90% for efficiency. These results show that it is an effective choice for biomass processing requirements. For Activity 3, the student assisted with the testing of the water wheel turbine using a DC generator. the power produced by the turbine lit up one 100W and one 25W 220V-AC bulb. For activity 4, the student assisted on the testing of the hydro vortex turbine. To produce more power output the student trainee helped modified the blade.
