Question
Electric current of 150 A is carried through a 5 mm diameter cylindrical wire which has a resistance of 0.003 ohm per meter length. The wire is exposed to a cross flow of air at 22°C and its surface temperature is measured as 30°C. In your calculations, take air properties at 300 K and use the following correlation and constants: Rep C m 0.4-4 0.989 0.330 hD Nup = k 4-40 0.911 0.385 C Re, PH %3D %3D 40–4000 0.683 0.466 4000 – 40,000 0.193 0.618 40,000– 400,000 0.027 0.805 Calculate the average heat transfer coefficient in W/m2K Calculate the air velocity in m/s
