Final answer:
To calculate the air and fuel mass flow rates, use the equation F = (m_dot_air + m_dot_fuel) * v_e, where F is the thrust force, m_dot_air is the mass flow rate of air, m_dot_fuel is the mass flow rate of fuel, and v_e is the exhaust velocity. Substituting the given values, the air mass flow rate is 72 kg/s and the fuel mass flow rate is 108 kg/s.
Step-by-step explanation:
To calculate the air and fuel mass flow rates, we need to use the equation:
F = (m_dot_air + m_dot_fuel) * v_e
Where F is the thrust force, m_dot_air is the mass flow rate of air, m_dot_fuel is the mass flow rate of fuel, and v_e is the exhaust velocity. We can rearrange this equation to solve for the mass flow rates:
m_dot_air = F / v_e
m_dot_fuel = (F - m_dot_air * v_e) / v_e
Substituting the given values:
m_dot_air = 180000 N / (2500 m/s) = 72 kg/s
m_dot_fuel = (180000 N - 72 kg/s * 2500 m/s) / 2500 m/s = 108 kg/s
