pipenostics v0.3.0

  • Active issues has been solved.
  • Function wth_d has been deprecated.
  • Breaking changes have been made to m325-tracers and flux-loss recalculations.
  • In appropriate functions the checkmate asserts specify ~0.29 mm as a minimum allowable value for pipe thickness wth.
  • In m325nhldata column diameter has been renamed to d that unifies it with b36pipedata column names.
  • Additional check for positivity of internal diameter now is made inside those functions which accept outside diameter and wall thickness as arguments.
  • Dataset m325nxdata now contains values of a-factor, pipe widths, and pipe diameters in mm, so that it’s valid b36pipedata data.
  • Function b36dwthv is introduced to perform validation of d/wth value pairs.
  • Functions m325nvl(), m325nml() are introduced to calculate normative material loss of heat carrierin pipe.
  • Issues with links in documentation are solved.
  • 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.

pipenostics v0.2.0

CRAN release: 2024-04-04

  • 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, and 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/m²].
  • The heat loss related terminology was clarified and adjusted: terms specific heat loss power, [kcal/m/h], and heat flux, [W/m²], are viewed separately while stay closely related. Term consumption replaced with flow_rate.
