I have been doing some work on this.. and i have came up with an answer, I am pretty sure its not right though..
Using Fourier's law:
Qx= -kA[T2-T1/L]
we know that the Qx is .15kW per 1 m^2, and the thickness of the concrete plane is .2 m
If .15kW of energy enter 1.0 m^2, then only...
A 0.2-m-thick plane wall is constructed of concrete. At steady state the energy transfer rate by conduction through a 1-m^2 area of the wall is 0.15 kW. If the temperature distibution is linear through the wall, what is the temperature difference across the wall, in K?
i don't even know where...
im sorry, t is from 0 to 2, used to writing x.. doesn't really matter what the variable is tho..
int. (t^2, t^4)^(1/2) is just stating the integral of that function... hence "int." for INTegral
what i have gotten for an answer the first time attempted i used U substitution pulling out a...
Need help solving the definite integral from 0<x<2 ||t,t^2||dt ( || = the norm of.)
so it really is
int. (t^2, t^4)^(1/2)
please and thank you.. i don't know why i can't get this.. but hellp pleaseee
