Cooling tower merupakan mesin pendingin air yang banyak digunakan pada industri, cooling salah satu instrumen cukup penting adalah alat pengukur suhu jalur output tower, mana umumnya masih menggunakan sika thermocouple pembacaan suhunya manual sehingga membatasi ruang lingkup pemantauan tower. Tujuan penelitian merancang dan menguji berbasis IoT dengan thingspeak channel sebagai penyedia layana...

Joule-Thomson cooling systems are used in refrigeration and liquefaction processes. There are extensive studies on Joule-Thomson cryogenic systems, but most of them coverage steady state conditions or lack from experimental data. In the present work, transient thermal behavior of Joule-Thomson cooling system including counter current helically coiled tube in tube heat exchanger, expansion valve...

application of cogeneration systems based gas turbine for heat and power production is increasing. because of finite natural energy resources and increasing energy demand the cost effective design of energy systems is essential. cgam problem as a cogeneration system is considered here for analyzing. two new approaches are considered, first in thermodynamic model of gas turbine and cogeneration ...

Large-scale U.S. dependence on thermoelectric (steam electric) generation requiring water for cooling underscores the need to understand controls on this water use. The study objective was to quantify water consumption and withdrawal for thermoelectric generation, identifying controls, using Texas as a case study. Water consumption for thermoelectricity in Texas in 2010 totaled ∼0.43 million ac...

We propose a scenario in which a large fraction, or even most, of the gas cooling to low temperatures of T < 10 K in cooling flow clusters, directly gains energy from the central black hole. Most of the cool gas is accelerated to nonrelativistic high velocities, vj ≃ 10 3 − 10 km s, after flowing through, or close to, an accretion disk around the central black hole. A poorly collimated wind (or...

The results of a CO line survey in central cluster galaxies with cooling flows are presented. Cold molecular gas is detected with the IRAM 30m telescope, through CO(1-0) and CO(2-1) emission lines in 6-10 among 32 galaxies. The corresponding gas masses are between 3.10 and 4.10 M . These results are in agreement with recent CO detections by Edge (2001). A strong correlation between the CO emiss...
