Question: Mass flows through a control volume (open system) at 1 kg/s. The enthalpy, velocity, and elevation at entrance are 200 kJ/kg, 30 m/s, and 100

Mass flows through a control volume (open system) at 1 kg/s. The enthalpy, velocity, and elevation at entrance are 200 kJ/kg, 30 m/s, and 100 m, respectively. At the exit, these quantities are 198 kJ/kg, 0.3 m/s, and –3 m. Heat is transferred to the system at a rate of 5 kJ/s. How much work done by this system
