Analysis of Power and Efficiency of Cross-flow Turbine Due to Changes in Runner Rotation

The Cross-flow turbine is one type of hydroelectric power plant that frequently used. This an experimental study with the goal analyzing and efficiency produced by as a result runner rotation adjustments. variations used are 261 rpm, 300 320 340 360 380 392 423 rpm head high 5 meters incoming water discharge 0.2 m3/s. best results shown when rotate at rpm. It's showed maximum 788.85 Watt 80.49%. proportional to rotational speed runner; higher runner's rotation, greater produced. To summarize, way achieve performance maximize rotation.
 Salah satu jenis pembangkit listrik tenaga air yang sering digunakan adalah turbin tipe Cross-flow. Penelitian ini berupa penelitian eksperimen bertujuan untuk menganalisis daya dan efisiensi dihasilkan akibat perubahan putaran runner. Variasi yaitu dengan setinggi meter serta debit masuk 0,2 Hasil menunjukkan maksimum didapatkan pada 788,85 80,49%. Terbukti bahwa sebanding kecepatan runner, semakin tinggi maka juga besar. Dapat disimpulkan, mendapatkan kinerja maksimal memaksimalkan
