This research investigates the changes of soil properties in Dasht-e Abbas plain due to the Karkheh water transfer to this plain. In thisstudy, the maps of groundwater level changes before and after the utilization of irrigation system were prepared. Furthermore, toinvestigate the changes of soil characteristics, soil samples were collected from various project implantations and control areas a...
An experimental investigation on heat transfer coefficient is presented from three horizontal tubes in a vertical array in a duct for 500<ReD<6000. A mass transfer measuring technique based on psychrometry chart is used to determine heat transfer coefficient. The diameter of the tubes is 11 mm each spaced 40 mm apart and in-line pitch ratio varies 
in the range 0.055<D/W<0.22. The experimen...
Comprehensive control of odors, hydrogen sulfide (H2S), ammonia (NH3) and odorous volatile organic compound (VOC) emissions associated with animal production is a critical need. Current methods utilizing wind tunnels and flux chambers for measurements of gaseous emissions from area sources such as feedlots, lagoons, pastures and cropland are often criticized for potential bias. The bias is due ...
