Question 1 Heat is transferred from hot, freshly cooked pasta to cold water it is rinsed in through: Conduction Convection Radiation

13.60 A furnace is located next to a dense array of cryogenic fluid piping. The ice-covered piping approximates a plane surface with an average temperature of T, = 0°C and an emissivity of ɛ, = 0.6. The furnace wall has a temperature of T,= 200°C and an emissiv- ity of ɛ, = 0.9. To protect the refrigeration equipment and piping from excessive heat loading, reflective aluminum radiation shielding with an emissivity of E, = 0.1 is placed between the piping and the furnace wall, as shown in the schematic. Assume all surfaces are diffuse-gray. Dense piping Furnace wall Tf = 200°C, e = 0.9 array, T, = 0°C, = 0.6 Installation criterion TNS 30°C -Radiation shields, N €, = 0.1 If the temperature of the shield closest to the piping T,N must be less than 30°C, how many radiation shields, N, must be installed between the piping and the furnace wall?

Using a polynomial equation solver, determine the steady-state surface temperature (Ts) of the passive radiative cooler below that is exposed to a windy convective enviroment h=40 W/m2*K and T∞= 25°C. The surrounding atmosphere is fixed at Tsur= 10°C. Set up the energy balance/conservation equation.
