BOD test bottles at the laboratory of a wastewater treatment plant. Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time period.
The organization is run by officers of Nepal Engineering Service (Building and Architecture) and accounts for a significant amount of national budget. The department has several offices, implementation units to implement its yearly programs and projects throughout the nation. [5] [6] [7] Project Office of Urban Development and Building ...
The Streeter–Phelps equation determines the relation between the dissolved oxygen concentration and the biological oxygen demand over time and is a solution to the linear first order differential equation [1]
The department has four major projects along with its central body at central level. Major hydro and multi-purpose projects including Sapta Koshi High Dam Multipurpose Project, Pancheshwar Multipurpose Project, Budhiganga Hydropower Project , Naumure Multipurpose Project and a few other projects also run under the department.
The Department of Local Infrastructure Development (DoLID), is a department under the Ministry of Urban Development of Nepal, responsible for assisting local governments in the engineering aspects of civil engineering construction including rural, urban and agriculture road/bridge construction and mentinance. [1] It has its branch offices. [2] [3]
The Ministry of Energy, Water Resources and Irrigation (Nepali: ऊर्जा, जलस्रोत तथा सिंचाइ मन्त्रालय) is a governmental body of Nepal that governs the development and implementation of energy including its conservation, regulation and utilization.
Once the friction factors of the pipes are obtained (or calculated from pipe friction laws such as the Darcy-Weisbach equation), we can consider how to calculate the flow rates and head losses on the network. Generally the head losses (potential differences) at each node are neglected, and a solution is sought for the steady-state flows on the ...
The department and its branch offices are run by officers of Nepal Engineering Service (Civil/Hydrology). [4] The department has 4 regional offices and several field offices for different river systems. A few other projects also run under the department. [5]
