Abstract

Water is one of the factors which very important and necessary in the life of living creatures. Therefore, water must be available whenever and wherever in the quantity, timing, and sufficient quality. Hydraulic Ram Pump (Hydram) is a pump does not require external energy as the power source. The purposes of this research are understanding the influence of falling angle from the hydrant pump toward generated debit and finding the influence of the falling angle of the hydrant pump to generated efficiency. This research uses hydrant pump by the specification of tube compressor its’ diameter 3 inches and a height 60 cm. the falling angle of pump are 35°, 40°, 45°, 50° and 55°. The falling-height is 1 meter  with five variations of weight-lift 3, 3½, 4, 4½, and 5 meters. The method of analysis is conducted by analyzing data obtained during the experiment, where the  results in the form of quantitative data which is presented in type of  tables and displayed in graphical form. The results of the research shows that  the best output debit on falling 35 ° namely 0.079 L / s  with 3 meters’ water weight-lift, while the lowest output debit on falling 55 ° namely 0.010 L / s 5 meters’ water weight-lift. The best efficiency is 6.103% in the falling angle of  35 ° with 3 meters’ of water weight-lift, while the lowest efficiency is 1.239% in the falling angle of 55 ° with 5 meters’ of water weight-lift.

Abstract

This paper presents the experimental data of the use of granite stone as an absorber of the tested solar colecctor. The purpose of this study is to know the effect of the cover thickness of the collector. Three different thickness of the glass cover of the collector, i.e. 3 mm, 5 mm, and 8 mm, were tested. Three identical collectors were utilized in this current study, and the collectors were placed facing North. The dimension of the granite absorber is 100 cm x 80 cm x 10 cm and the arrangement of the pipes in the collector is parallel with 7 pipes. The water used to remove the heat from the absorber was flowed naturaly due to the gravity. The water volumetric flow rates employed were 300 cc/min, 400 cc/min and 500 cc/min which were measured using a glass volume meter and a stop watch. The research results show that energy come to the absorber (Qin), energy absorbed by the absorber (Quse), and the temperature of water increase with the time. All of them have a peak at around 12.00-14.00 Wita. The thicknes of the glass cover affect the performance of the collectors. The glass cover thickness of 5 mm results in the better performance than that of the two others.

Abstract

Sebagaimana energi fosil telah mulai berkurang, maka sangat penting untuk memanfaatkan energi alternatif seperti energi surya. Suatu peralatan yang dapat digunakan untuk menangkap dan mengubah energi surya adalah kolektor surya. Dua kolektor surya identik digunakan dalam penelitian ini ditempatkan menghadap ke Utara dengan sudut kemiringan 15 °. Dimensi kolektor adalah 0,8 m x 1 m x 0,05 m. Salah satu kolektor yang terdiri dari 5 pipa paralel dan lainnya yang terdiri dari  7 pipa paralel. Air yang digunakan dalam percobaan ini  mengalir secara alami karena gaya gravitasi dari tangki yang lebih tinggi dan diatur  dengan katup dipasang pada sisi keluaran kolektor. Laju aliran air yang digunakan adalah 200, 250 dan 300 cc / menit dan diukur dengan menggunakan gelas ukur  dan stop watch. Hasil penelitian menunjukkan bahwa energi yang masuk ke kolektor, energi yang diserap oleh absorber dan air, naik dengan meningkatnya  waktu observasi dan mencapai nilai puncak pada sekitar pukul 02:30 Wita. Setelah itu, menurun. Pengaruh jumlah pipa adalah tidak signifikan.  Kata kunci: kolektor surya, absorber batu granit, performa kolektor
