Calculate the steady state creep rate for the turbine material under its operating conditions of temperature and stress if:
Hint: be careful of units. In this case, it would be easier to keep things in h (hours) and MPa because of the K2 parameter. Also remember to convert to absolute temperature (add 273.15 to the temperature in °C) and note the kJ (in other words, multiply by 103) part of the activation energy parameter. Enter three significant figures. Use the "e" scientific notation, for example if your answer is 1.55 × 10-10, input the scientific notation 1.55e-10. /
Bereken die bestendige toestand kruiptempo vir die turbinemateriaal onder sy werkstoestande van temperatuur en spanning indien:
Wenk: wees versigtig vir eenhede. In hierdie geval sal dit makliker wees om dinge in h (ure) en MPa te hou as gevolg van die K2-parameter. Onthou ook om na absolute temperatuur om te skakel (voeg 273.15 by die temperatuur in °C) en let op die kJ (met ander woorde, vermenigvuldig met 103) deel van die aktiveringsenergieparameter. Voer drie tellende syfers in. Gebruik die "e" wetenskaplike notasie, byvoorbeeld as u antwoord 1.55 × 10-10 is, voer die wetenskaplike notasie 1.55e-10 in.
