“…Dengan hukum fisika, air dengan sendirinya mengalir dari tempat yang tinggi ketempat yang lebih rendah. Namun kenyataannya permukaan tanah tidak selalu datar atau rata, ada yang bergelombang dan lain sebagainya dan yang permukaan tanahnya lebih tinggi dari sumber air akan lebih sulit untuk mendapatkan pasokan air secara kontinyu [1] [2]. Namun jumlah air relative tetap, sementara kebutuhan air sangat meningkat maka dari ketersedian dan permintaan air perlu dikelola sedemikian rupa, sehingga air dapat disimpan jika berlebihan dan dapat dimanfaatkan saat dibutuhkan.…”

Penelitian ini dilakukan untuk memberikan penjelasan tentang studi eksperimental pengaruh variasi beban dan variasi aliran terhadap efek water hammer. Dimana efek ini akan mempengaruhi tekanan air yang akan dihasilkan jika setelah pembebanan dan perubahan bukaan valve yang diberikan akan menghasilkan efek water hammer yang lebih baik atau cenderung lebih buruk bila tidak memiliki kedua efek tersebut. Penelitian ini dilakukan dengan melakukan studi eksperimental yang bertujuan untuk mengetahui tekanan yang terjadi pada saat air mengalir dan kemudian ditutup secara tiba-tiba oleh katup pembuangan yang dihubungkan dengan aliran pipa dengan diameter 1,5 inci setelah beban dan variasi bukaan katup. Pada uji efek water hammer dengan sistem pompa water hammer hidrolik ini dimungkinkan untuk mengubah bukaan katup pemasukan air dengan perubahan beban katup yang diberikan untuk menentukan tekanan water hammer maksimum 378334,64 Pa setelah menerima katup bukaan 80 derajat dan tambahan beban 250 gr, dan efek water hammer terkecil dengan nilai 321376,44 Pa pada bukaan katup 50 derajat dan beban 150 gr. Saat menginvestigasi pompa hydraulic ram ini, dapat disimpulkan bahwa ukuran bukaan valve atau jumlah air yang masuk dan besarnya beban pada discharge valve yang akan mempengaruhi tekanan akan meningkat.

Geographically, Indonesia is an agricultural country. It greatly supports agricultural production. So that the quality and commodity of agricultural products (soybean) remains high, it is necessary to have new ideas or ideas, one of which is by processing tempeh chips to become quality. It prompted researchers to develop innovative equipment that can speed up the tempe chopping process by creating an appropriate technology machine that can produce more optimal chopped tempeh compared to the conventional method, which is 30 kg/hour. This appropriate technology machine is implemented in UKM chips tempeh, Sukomanunggal sub-district, Surabaya City. The machine can help speed up the process of chopping tempeh so that production time can be optimally increased.

“…There are various film-type cooling tower fill designs available, consisting of different geometries of obstacles such as corrugated, 3 wave surface, straight, and zig-zag type fill. 4 Each has a varying effect on fluid film rate and airflow. However, the most certainty is that they increase the pressure drop of the cooling tower system.…”

A multi-faceted vertical rib has been numerically investigated using the internal flow of rib in a rectangular channel method under turbulent flow for 17,000 < Re < 27,000. The vertical rib that can be encountered inside porous media design often creates a persisting issue of high-pressure drop. The challenge frequently intensifies, mainly when a two-phase state heat transfer is introduced inside the porous media. The vertical multi-faceted rib models the various surfaces often encountered inside the porous media. The effect of blockage ratio on the flow characteristics and thermal performance is observed. The results are compared to the more conventional circular rib, equal in surface area to the multi-faceted rib. The multi-faceted rib yields a higher average Nusselt number of approximately 33% and contributes to the higher average Nusselt number of the channel. The multi-faceted rib channel has a better thermal performance factor, in average of approximately 13% higher and lower pressure drop than the circular rib channel. The advantage of the multi-faceted rib is attributed to, surprisingly, the poor flow attachment on the rib surface, which results in a low Cf/ f ratio. Consequently, the multi-faceted rib suffers from very low velocity on the downstream rib surface. Ultimately, the spatial effect of the rib inside the square channel can be evaluated using the Cf/ f ratio, which takes into account the rib surface and channel walls. In the quasi two-phase state, the circular rib is observed to provide a more favorable condition for latent heat transfer under extreme condition investigated.
