  5. A 40KW 3 phase 400v, resistance oven is to employ nichrome strip 0.25mm thick for the three star-connected heating elements. If the wire temperature is to be 1200C and that of the charge is to be 800C, estimate a suitable width for the strip. Assume emissivity= 0.9 and radiating efficiency=0.5. Also determine the temperature of the wire when the charge is cold.
  6. What are the factors which limit the choice of frequency in induction and dielectric heating?
