temperature at a depth of 7.5 cm 4 min after the surface temperature is changed

7. A dryer is shaped like a long semicylindrical duct of diameter 1.5 m. The base of the dryer is occupied with water-soaked materials to be dried. The base is maintained at a temperature of 370 K, while the dome of the dryer is maintained at 1000 K. If both surfaces behave as blackbodies, determine the drying rate per unit length experienced by the wet materials.

Explain the difference (in concept or definition) between boundary layer thickness and thermal boundary layer thickness?

Problem 5: Questions Determine the capacitance in uF of a parallel plate capacitor having a plate area of 0.03 m and a plate separation of 0.2 um. The dielectric has a dielectric constant of 7. If the Capacitance is C-25mF, what is the distance between the two plates? Use same other values. Determine the inductance of a coil with 400 turns on a core that is 2 cm long and hasa diameter of 1 cm. The permeability (not the relative one) is 0.25 mH/m.
