Temperature response in cooling a wire. a small copper wire with a diameter of 0.792 mm and initially at 366.5 k is suddenly immersed in a liquid held constant at 311 k. the convection coefficient h = 85.2 w/m2 · k. the physical properties can be assumed constant and are k = 374 w/m · k, cp = 0.389 kj/kg · k, and rho = 8890 kg/m3. determine the time in seconds for the average temperature of the wire to drop to 338.8 k (one-half the initial temperature difference).do the same but for h = 11.36 w/m2 · k. for part (b), calculate the total amount of heat removed for a wire 1.0 m long.
