The Modified Arkansas Off-Stream Reservoir Analysis (MARORA) model estimates the economics of on-farm reservoirs and other water conservation improvements in alternative ground water situations. With restricted ground water supply, a combination of different water conservation methods is estimated to provide the greatest economic return. On-farm reservoirs are not economical if ground water is ...

Abstract Pressure drop and flow pattern of oil–water flows were investigated in a 19-mm ID clear polyvinyl chloride pipe consisting U -bend with radius curvature 100 mm. The range for oil water superficial velocities tested was $$0.04 \le U_{{{\text{so}}}} 0.950 \;{\text{m/s}}$$ 0.04≤<...

Although inlet bent pipes are usually adopted due to limited installation space, the influences of different bend on flow characteristics and performance centrifugal compressors still unclear. The numerical simulation a compressor is established validated by experimental results with case straight pipe. Then, internal 90-degree pipe (p90) Z-shaped (pz) simulated discussed. show that adoption tw...

The authors evaluations using CFD analysis to calculate the rate of pipe bend erosion utilised in fluid-circulating technological installations along with solid particles on small size nature bottom ash are described this work. examined bends have various degrees curvature and same wall thickness diameter is made stainless steel. regions values main goals study. extrados where mostly happens. t...

This work deals with the application of temperature oscillation method to measure local values heat transfer coefficient in laminar flow a straight horizontal pipe and bend. method, applied here for first time such experimental conditions, uses time-varying flux as boundary condition, which is condition third kind. Since an analytical solution conditions could not be identified existing literat...

Transmission and distribution pipelines have a significant role in the oil and gas industries. Pipelines are facing different threat like corrosion, improper design and incorrect operation. Gas vapor released from a pipeline (owned by NIOC) failure spread out and reached to ignition source. Due to gas outdoor spreading, “flash fire” occurred and flame return caused “vapor cloud explosion” of ga...

The safe operation of petrochemical plant requires screening of the pipework to ensure that there are no unacceptable levels of corrosion. Unfortunately, each plant has many thousands of metres of pipe, much of which is insulated or inaccessible. Conventional methods such as visual inspection and ultrasonic thickness gauging require access to each point of the pipe which is time consuming and v...
