This note describes continued studies at Fermilab of the long term stability of a small water Cerenkov tank. The water tank, bag liner, water, photomultiplier tube, and data acquisition software were unchanged for the additional measurements from June to November, 1999. However, some details of the geometry of the trigger counters relative to the tank and of the electronics may have differed. T...

This paper describes a tank-scale test setup and experimental methodology used to investigate coupled heat transfer water flow processes during heating of compacted MX80 bentonite high temperatures. Specifically, temperature 200°C was maintained by cylindrical element at the center layer containing an array temperature, dielectric, relative humidity sensors. In addition providing evaluation spa...

The present study deals with the thermal performance evaluation and economic analysis of a low-cost modified flat-plate solar water heater (SWH) with a parallel two-side serpentine flow. This is a unique inexpensive and easily fabricated SWH having better thermal efficiency than those investigated by earlier authors. The solar water heating system is having parallel two-side serpentine arrangem...

This study deals with one of frequently encountered tasks in process industry – accurate water level control. Proportional Integral Derivative (PID) control is often used for this purpose. Since control parameters of PID controller are fixed and tank system is inherently nonlinear, PID controller should not be used on wider level range. Therefore this study analyzes the effectiveness of water l...

Water tank is used extensively for storing water, inflammable liquids and other chemicals. Generally, to provide water at large, tank is supported on frame or shaft (a vertical cylindrical shell). The staging with a single row of columns placed straight (vertical) along the periphery of circle or shaft, are generally adopted for elevated water tanks to support the tank container. Apart from ver...

Analysis of the work, which considered mathematical modeling melting process in various industries, currently does not pay attention to processes heating and hydrocarbon mixtures, such as vaseline, paraffin, fats, lanolin others. The issue optimization processes, calculations necessary parameters (speed depth thermal front penetration, etc.) equipment, avoidance repetition for each mixture expe...

Total microbial quality assessment and geographical information system were used for evaluating the quality of water and the spatial distribution of diarrhoea cases in Tshikuwi, a rural community in South Africa, during an outbreak of diarrhoea. The water-abstraction points included two groundwater storage tanks, namely Tank 1 and Tank 2 and the Khandanama river. Indicator microbial counts for ...

BACKGROUND Lowering water heater temperature set points and using less drinking water are common approaches to conserving water and energy; yet, there are discrepancies in past literature regarding the effects of water heater temperature and water use patterns on the occurrence of opportunistic pathogens, in particular Legionella pneumophila. Our objective was to conduct a controlled, replicate...

Fast transient microboiling has been characterized on modified gold microheaters using a novel laser strobe microscopy technique. Microheater surfaces of different hydrophobicity were prepared using self-assembled monolayers of hexadecane thiol (hydrophobic) and 16-mercaptohexadecanol (hydrophilic) as well as the naturally hydrophilic bare gold surface. The microheater was immersed in a pool of...
