Pengaruh Diameter Nozzle terhadap Prestasi Turbin Air Pelton

Abstract

This essay discussed the influence of the diameter of the nozzle, fluid flow, fluid flow velocity and mass flow rate of the fluid to the power output of the turbine pelton. To perform the analysis carried out tests with a nozzle diameter of 2 mm, 2.5 mm, 3 mm with valve openings at 300. At any difference fluid flow nozzle size will have a difference anyway at the point of maximum flow rate in the valve openings. At the nozzle 2 mm diameter nozzle known that fluid flow discharge valve 300 which is about m3/s with a round generated approximately 955 RPM. At the nozzle diameter 2.5 mm, the resulting discharge occurs in the valve opening 300 produce flow rates of about m3/s with a round generated 1203 RPM. At the nozzle diameter 3 mm, discharge generated occurs in the valve opening 300 to produce flow rates of about m3/s with a round generated 1320 RPM. Nozzle diameter size affect the amount of fluid flow, fluid velocity, fluid flow rate and rotation turbine blades thus also affect the value of the electrical power input that will be produced on this Pelton Turbine
