A 40-Cm-Long, 0

A 40-cm-long, 0.6-cm-diameter electric resistance wire is used to determine the convection heat transfer coefficient in air at 25°C experimentally. The surface temperature of the wire is measured to be 150°C when the electric power consumption is 90 W. If the radiation heat loss from the wire is calculated to be 30 W, the convection heat transfer coefficient is

A) 0.48 W/m².°C
B) 127 W/m².°C
C) 63.7 W/m².°C
D) 95 W/m².°C
E) 200 W/m².°C "
