A number 14 copper wire has a diameter of 1.628 mm. Calculate the resistance of a 34.0 m long piece of such wire. (Use 1.72×10-8 Ωm for the resistivity of copper.) 2.809×10-1 Ohm For safety, the National Electrical Code limits the allowable amount of current which such a wire may carry. When used in indoor wiring, the limit is 15.0 A for rubber insulated wire of that size. How much power would be dissipated in the wire of the above...

A 400-W cylindrical resistance heater is 1 m long and 0.5-cm-diameter. The resistance wire is placed horizontally in a fluid at 20◦C, flowing at a velocity of 20 m/s. Determine the outer surface temperature of the resistance wire in steady operation if the fluid is (a) air and (b) water. Ignore any heat transfer by radiation and evaluate properties of air at 800 K and properties of water at 315 K.
