The mass flow rate of air through an aircraft engine is $10 \mathrm{~kg} / \mathrm{s}$. The compressor outlet temperature is $400 \mathrm{~K}$ and the turbine inlet temperature is $1800 \mathrm{~K}$. The heating value of the fuel is $42 \mathrm{MJ} / \mathrm{kg}$ and the specific heat at constant pressure is $1 \mathrm{~kJ} / \mathrm{kg}-\mathrm{K}$. The mass flow rate of the fuel in $\mathrm{kg} / \mathrm{s}$ is approximately_____________
