Discussion Overview

The discussion centers around the challenge of plotting the relationship between the variables T1 and T2, given the equation 0.02q = T1 - T2. Participants explore methods for graphing these variables while considering the variable q.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses difficulty in plotting T1 and T2 due to their dependence on the variable q and seeks methods to approximate q as a constant.
  • Another participant suggests viewing (T1 - T2) as a single variable (delta temperature) and proposes plotting q as the dependent variable against (T1 - T2).
  • A different participant acknowledges the possibility of plotting the difference (T1 - T2) against q but reiterates the need to plot T1 directly against T2.
  • Another suggestion is made to plot T2 as a function of T1 using either a 3D plot with T1 and q as independent variables or a 2D plot with parallel lines for different values of q.

Areas of Agreement / Disagreement

Participants express differing views on how to approach the plotting of T1 and T2, with no consensus reached on a single method. Multiple competing ideas for graphing are presented.

Contextual Notes

Participants have not resolved the issue of how to effectively represent the relationship between T1 and T2 given the variable nature of q, and assumptions regarding the constancy of q remain unaddressed.

Who May Find This Useful

Individuals interested in graphing relationships in thermodynamics or those working with equations involving multiple variables may find this discussion relevant.

i have an equation 0.02q=T1-T2

how do i plot a graph between T2 and T1...since all the three are variables i am not able to plot the graph between T2 and T1...kindly help...is der any method to approximate variable q to a constant? so dat i can plot the graph

If you think of (T1 - T2) as a single variable (delta temperature), you have an equation of a line and could plot q as the dependent variable vs (T1 - T2) as the dependent variable.
 
taking t1-t2 as difference of T we could sure plot a graph between diff(T) Vs q...but i need a plot btw T1 and T2...
 
If you want plot T2 as a function of T1, there are a couple of options. One is a 3D plot where the independent variables are T1 and q. In this case the plot will be a planar surface. Another option is in a 2D plot consisting of a series of parallel lines with each line corresponding to a different value of q.
 
Thank you for the reply.
