Okay thanks. I finished this problem before I posted it on here. I was just looking for a method that involved separation and integration. In my original solution (which was successful), I had to make a T(x) equation. I was trying to look for a method that didn't involve this.

Where do you see somewhere where T(x). There is no function for that. Can only use the information given.

Homework Statement Q=-1*K(T)*(H*W)*(dT/dx)+((I^2)(p)(dx)/(H*W)) K(T)=(197.29-.06333333(T+273)) H=0.01905 W=0.06604 I=700 p=10*10^-6 Q=some constant Please separate and differentiate to solve for Q using variables of T and x. Boundaries: T: Upper=T1 (constant) Lower=T0 (constant) x: Upper=L...

Homework Statement So I have a problem where I have a series and two other parallel insulators bringing a system from a temperature of Tzero to Ttwo. However, the two aforementioned temperatures have a huge difference thus causing kappa to vary with temperature. I am trying to know how to...

i am sure i did it wrong. I just want to know how to do it right.

but i did it wrong. If you do it the same way, you will know you did it wrong like me when you read it

Homework Statement A passenger train is traveling at 27 m/s when the engineer sees a freight train 366 m ahead of his train traveling in the same direction on the same track. The freight train is moving at a speed of 5.9 m/s. (a) If the reaction time of the engineer is 0.39 s, what is the...
