Pipa pesat merupakan saluran penghubung antara bak penenang
dengan turbin pada rumah pembangkit. Meminimalisir kehilangan
energi pada pipa pesat sangat penting untuk mengoptimalkan
bangkitan energi listrik. Tujuan penelitian ini adalah melakukan
optimasi diameter dan tebal pipa pesat untuk mencari hasil yang
paling efisien, yang dikaji dari aspek hidrolika dan biayanya.
Metode pemilihan pipa pesat yang optimal dapat ditentukan
berdasarkan hubungan secara empiris, antara berbagai formula dari
diameter dan tebal pipa pesat yang dinilai terhadap energi yang
dihasilkan serta harga pipa pesat itu sendiri. Hasil penelitian
menunjukkan bahwa besar diameter berbanding lurus dengan besar
energi yang dihasilkan dan harga pipa pesat. Berdasarkan
perbandingan, didapatkan diameter optimum pipa pesat sebesar
0,45 meter dengan tebal 0,0018 meter yang dihitung menggunakan
formula dari Moffat, serta daya bangkitan sebesar 52,16 kW dan
energi sebesar 456.914,33 kWh per tahunnya dengan harga pipa
IDR 3.610.900 per meter pipa pesat.
Penstock is the connecting channel between the forebay and the
turbine in the power house. Minimizing the energy loss in the
penstock is very important to optimize the generation of electrical
energy. The purpose of this research is to optimize the diameter
and thickness of penstock to find the most efficient results, which
are examined from the aspects of hydraulics and costs. The optimal
method of penstock selection can be determined based on the
empirical relationship between the various formulas of the diameter
and thickness of the penstock as assessed by the energy produced
and the price of the penstock itself. The results showed that the
diameter was directly proportional to the amount of energy
produced and penstock price. Based on the comparison, the
optimum diameter of the penstock is 0,45 meters with a thickness
of 0,0018 meters which is calculated using the formula from
Moffat, as well as a generation power of 52,16 kW and energy of
456.914,33 kWh yearly with the price of IDR 3.610.900 per meter
penstock pipe.
