Crossflow turbine is a type of turbine that often used as a prime mover in MHP system. this
type of turbine has an advantage witch can be applied in low head with high water discharge. The
output power from this turbine is effected by the number of blades that installed on the tubine runner.
The aim of this study is to hold an experimental study of the number of blade that used on crossflow
turbine to get the maximum output power. The number of blade that used is 10, 14, 18, 22, and 26
blades. Where from the result of calculations, it is found that turbine with number of blades 18 has
the higest efficiency with a value of 8,52%.
