... Abstract Measurement uncertainty is increasingly seen as essential in quality assurance for industry. The uncertainty associated with a value of a physical quantity provides a quantitative measure of the reliability and trustworthiness of that value. The ISO Guide to the Expression...

... limits of these equations were examined to obtain expressions for when the pipe is touching the ground surface and the expressions were found to coincide. Good success is indicated as the fully buried shape factor was found to agree with numerical results to within 2.5%. Scarcity of numerical data...

... curve. These curves are all common water displacement curves, each reflecting only one rule of water-cut rise. Based on our theory of generalized water displacement curve (GWDC), where the curve can reflect various rules of water-cut rise, we have presented a new GWDC expression: l g N p =a-blg(L p...
