The paper describes the detailed techno-commercial analysis done on a 46 m2 solar air heating system developed in a food processing industry. The solar air heating system was connected to an indoor drier through a duct. A detailed performance analysis was undertaken on the system by loading with 75 kg of ripe mango flake. The product loaded was uniform in size having a thickness of 4mm. On a cl...

Low-impact development (LID) practices are gaining popularity as an approach to manage stormwater close to the source. LID practices reduce infrastructure requirements and help maintain hydrologic processes similar to predevelopment conditions. Studies have shown LID practices to be effective in reducing runoff and improving water quality. However, little has been done to aid decision makers in...
