| Abstract | A steady and kinematic thermal conductivity measurement method is proposed for the round tube flow in laminar regime under constant heat flux condition. And this method is based on the fact that heat transfer coefficient depends only on thermal conductivity λ and inner diameter and is independent of V, ρ, and Cp in laminar flow with fully developed temperature and velocity profile. This independence results from the fact that the energy transport is purely molecular conduction problem under these conditions. The uncertainty of the measurement is within ± 3.0 % (coverage factor k = 2) according to the uncertainty analysis. For validation, the thermal conductivity of toluene and ethanol was measured at the temperature range of (288–372) K. And the validation tests show that the relative deviation of measured thermal conductivity from standard data is within an error band of 2 %. Using this method, thermal conductivity of a typical hydrocarbon aviation fuel RP-3 was measured. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
