WebChromium (atomic symbol: Cr, atomic number: 24) is a Block D, Group 6, Period 4 element with an atomic weight of 51.9961. The number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electron configuration … WebAddition of 20% chromium offers adequate electric resistance for heating systems. The …
WebTranscribed image text: Problem 2.1 : A 15 kW, 220 V single phase resistance oven employs nickle-chrome wire for its heating elements. If the wire temperature is not to exceed 1000 °C and the temperature of the charge is to be 600 °C, calculate the diameter and length of the wire. Assume radiating efficiency to be 0:6 and emissivity as 0.9. WebSo, if the Area of the silencer is 220 square inches, and the equivalent length from the cathode to the anode is, say, 4 inches, the resistance is 0.058 ^ 0.0228 ohms, and 9.9 ^ 3.9 volts will be required for plating, although I suspect that the resistivity of a chrome plating solution at operating temperature is less than 3.18 ohm-cm. Good luck.
