Please help me with this problem
2. A composite cylinder is formed by a long cylindrical rod (A) and two concentric cylinders (tubes B and C). Tube B encloses trod A and its inner and outer radii are 20 mm and 40 mm, respectively. Tube C encloses tube B and its outer radius is 50 mm. A thin electrical heater is inserted between rod A and tube B. The rod (A) has a thermal conductivity of 2.5 w/m K, while...

answer.
3.57 A composite cylindrical wall is composed of two materials of thermal conductivity k and kp, which are separated by a very thin, electric resistance heater for which interfacial contact resistances are negligible. Resistance heater r2 Internal flow T h A Ambient air T h Liquid pumped through the tube is at a temperature Ta and provides a convection coefficient h, at the inner...

Chenical reaction, Figure 1: Two end of the rods are maintained at different temperatures A chemically reacting mixture is stored in a thin-walled spherical container of radius 1 200 mm, and the exothermic reaction generates heat at a uniform, but temperature-dependent volumetric rate of q exp( A/T ), where如= 500 W/m3. A = 75 K. and To IS the mixture teinperature in kelvins. The vessel is enclosed by an insulating material of outer radius r2, thermal conductivity k, and emissivity...
