Problem X2-6, Heat Transfer, Spring 2018 Heat is being generated uniformly throughout a sphere at volumetric rate i. The radius of the sphere is R and the sphere is made of a material having thermal conductivity k . The temperature at the surface of the sphere is Assume one- dimensional steady conduction in the radial direction and do the following: a) Use the equation (2.14 b) for in spherical coordinates and the...

Transient Conduction 1. (10 pts) The corner of a rectangular object experiences convection on its left and top sides, as shown below. Initially, the object experiences no heat generation and has a steady uniform temperature of Ti. Suddenly, at t 0, a chemical reaction takes place throughout the volume of the material, which causes heat generation (q"). Using the energy...

Need help with part B (the sketching!) thanks
Problem 3: A thin flat plate of length L-120 mm, thickness t=4 mm, width W=30 mm, and thermal conductivity k=20 W/m-K is thermally joined to heat sinks at different temperatures, where T(x = 0) = To-100 C and T(x = L) = T,-35°C. The top surface of the plate is subjected to uniform heat flux q"-20 kW/m2, and the bottom surface of the plate is subjected to uniform convection with a convection...

1. (10) A door is receiving a constant heat flux of 10 kW/m2 from a fire in a room. The other side of the door is cooled by convection to air with T 25 C with a heat trans fer coefficient of 30 W/m2-C. The door is made of oak and is 4 cm thick. Use the 1-D heat equation to find the temperature distribution in the door. (Hint: you need to integrate the Heat Equation and then apply the...
