Perbandingan Stack Effect Pada Rumah Secara Konveksi Paksa Dan Konveksi Alami Ketika Kondisi Hujan

A room or a house is modified by setting a stack (chimney) to take the advantage of the phenomenon of stack effect. This stack is useful for air circulation so that the room become comfortable. The difference of colour on the outside wall of the house will also affect the room temperature because the stored thermal energy in the house will be different. The darker house wall will keep more thermal energy than the brighter. Meanwhile, the house that uses exhaust fan will keep less thermal energy than a house that did not use any exhaust fan. The high of required stack effect phenomenon can be calculated based on the stored thermal energy of the room. In the miniature house using exhaust fans, the chimneys or towers should be put at the 0.55-meter-high roof to a house without a paint, 0.35 meter for the white-painted house, 0.55 meter for the gray painted house, and 0.36 meter for the yellow-painted house. While for house miniature without exhaust fan (naturally), chimney should be placed to the 0.86-meter-high roof for the house without paint, 0.74 meter for the white-painted house, 0.85 meter for the gray painted house, and 0.75 meter for the yellow-painted house

Kaji Eksperimental Aliran Dua Fase Water-crude Oil Melewati Pipa Sudden Expansion Horisontal Berpenampang Lingkaran

Penelitian ini bertujuan untuk mendapatkan karakteristik dan penurunan tekanan pada pipa Pembesaran mendadak dengan rasio diameter 16:26 mm untuk aliran campuran air-crude oil. Variasi yang diberikan berupa penambahan fraksi volume minyak dalam aliran hingga 10% serta laju aliran yang didasarkan pada putaran motor pompa 2400, 2200, 2000, 1800, 1600, dan 1400 rpm. Nilai penurunan tekanan dihitung dari data perbedaan tekanan antara pipa kecil dan besar pada daerah sudden expansion yang diukur dengan manometer U, sedangkan debit aliran diukur menggunakan flow meter. Hasil penghitungan penurunan tekanan pada daerah sudden expansion berkisar antara 250-980 Pa. sedangkan penambahan fraksi volume crude oil sangat berpengaruh terhadap debit aliran, hasil perhitungan debit aliran yang berkisar antara 0,00028 m3/s-0,00065 m3/s
