Heat Transfer - Chapter 2 - Example Problem 6 - Solving the Heat Equation in Cylindrical Coordinates 

You are a god, a heat transfer god.

Consider the heat transfer fluid flow with constant thermophysical properties and a steady state in the space between two concentric cylinders. The inner cylinder is solid and has a radius of 1r and the outer cylinder is hollow with an inner radius of 2r. It is desirable to determine the heat flux and recovery coefficient for the cases where the pressure gradient is not considered or the pressure gradient is considered: a. Examine all possible states (ie 1zV and 2 zV in the same direction, different directions, 10zV and 20 zV and vice versa.

Take my like. You deserve it.

How would you solve for a system with r and y heat flow?

Hey where can I get the texted answer for this

how can i solve this problem below ????

thank you

thanks

Outter surface loses heat by convection to the surrounding. You didn’t add this part

How I can thank u
