Two field experiments were performed to evaluate the performance of electrical resistance tomography (ERT) as a leak detection method under metal underground storage tanks (UST). This paper provides a summary of the field experiments performed under a 15 m diameter steel tank mockup located at the Hanford Reservation, Washington. Two different leak events were created. About 3800 liters of sali...

It is important to evaluate whether an ice thermal storage system can operate effectively as the way planned at the design stage. While designing an ice thermal storage system, generally, the thermal storage time is calculated by using rated capacity of refrigerator or the heat exchange capacity of ice-on-coil, and the heating capacity time is calculated by using the average ice melting ability...

In combination with seasonal thermal energy storage (STES), solar offers a vast potential for decarbonizing the residential heat supply. this work, parametric optimization is conducted to assess of reducing costs water-based STES through use alternative insulation materials and integration an underground outside building. The investigated configurations include: hot-water tank, collector instal...

Burkholderia pseudomallei was isolated from environmental specimens 1 year after an outbreak of acute melioidosis in a remote coastal community in northwestern Australia. B. pseudomallei was isolated from a water storage tank and from spray formed in a pH-raising aerator unit. Pulsed-field gel electrophoresis confirmed the aerator and storage tank isolates were identical to the outbreak strain,...

This paper presents efflux time experiments performed in the absence and presence of aqueous solutions of Drag Reducing Agents (DRAs) when a liquid is emptied from a large open cylindrical storage tank through an exit piping system. The drag reducing agents studied are Dodecyl benzene sulfonate anionic surfactant and a mixed solution of surfactant and sodium chloride counter ion. The variab...

In systems experiencing water scarcity and consequent intermittent supply, users often adopt private tanks that collect water during service periods and supply users when the service is not available. The tank may be fed by gravity or by private pumping stations depending on the network pressure level. Once water resources are collected, the tank can supply users by gravity if it is located on ...
