To calculate the gross thrust, we need to use the following formula:<br /><br />Gross Thrust = (Air mass flow rate * Specific heat capacity of air * Temperature change) + (0.5 * Air density * Velocity^2)<br /><br />Given information:<br />- Air mass flow rate (m_dot) = 137485 kg/s<br />- Specific heat capacity of air (c_p) = 1005 J/kg-K<br />- Temperature change (T_2 - T_1) = 5 K<br />- Air density (ρ) = 1.225 kg/m^3<br />- Velocity (V) = 2 m/s<br /><br />Substituting the values in the formula:<br /><br />Gross Thrust = (137485 kg/s * 1005 J/kg-K * 5 K) + (0.5 * 1.225 kg/m^3 * (2 m/s)^2)<br /><br />Gross Thrust = 344,762.5 J/s + 4.9 J<br />Gross Thrust = 344,767.4 J/s<br /><br />Therefore, the gross thrust is 344,767.4 J/s.
