pipenostics 0.2.1

Backlog

• add data to b36pipedata from API 5L Tables
• deprecate function wth_d
• spread diameter d and wall thickness wth checkmates to all functions with those arguments
• add rulc - remain useful life calculator

Current version

• cosmetic improvements to documentation
• datasets api5l3t and m325testbench are renamed to api5l3tdata and m325nxdata appropriately for the purpose of unification with dataset naming rules
• functions b36mass(), b36wth() b36d() are introduced to calculate mass and geometric characteristics of actually manufactured pipes
• nominal specifications of the manufactured pipes now are represented in b36pipedata-dataset

Version 0.2.0

• where possible and justified, support for multi-threaded data processing, based on the capabilities of the parallel package, has been added.
• functions for determining the state of water and steam (IAPWS) have been excluded from the package due to the decision to use the built-in functions from iapws-package imported from CRAN.
• set of functions mgtdhid(), mgtdhidt(), mgtdhgeo(), mgtdhgeot() are introduced to interface with Modified Ground Temperature Double Harmonic Model.
• function meteos() is introduced to get a list of weather stations
• functions geodist() and geoarea() for calculating geographical metrics are added.
• functions traceline(), tracefw(), and tracebw() were added to process district heating networks with user-provided heat loss.
• job log of m325tracefw() now does not contain duplicated traced flow paths.
• job logs of m325tracefw() and m325tracebw() now contain loss, flux, Q.
• function m325tracebw()now can trace partially sensor-equipped district networks.
• functions m325dropt() and m325tracebwm() were excluded.
• functions flux_loss() and loss_flux() were added to convert between specific heat loss power, [kcal/m/h] , and heat flux, [W/m^2].
• the heat loss related terminology was clarified and adjusted: terms specific heat loss power, [kcal/m/h], and heat flux, [W/m^2], are viewed separately while stay closely related. Term consumption replaced with flow_rate.
