A tungsten wire used in a constant current hot wire anemometer has the following parameters :
Resistance at $0^\circ C$ is $10\Omega$, Surface area is $10^{-4}m^2$, Linear temperature coefficient of resistance of the tungsten wire is $4.8\times10^{-3}/^\circ C, $ Convective heat transfer coefficient is $25.2W/m^2/^\circ C,$ flowing air temperature is $30^\circ C$, wire current is $100 mA$, mass-specific heat product is $2.5\times 10^{-5} J/^\circ C$
At steady state, the resistance of the wire in $\Omega$ is
- $10.000$
- $10.144$
- $12.152$
- $14.128$
