5. A generator produces electricity from a water tank as shown. Determine the electrical output from the generator as a function of water level (h) for the following flow rates: 2.5, 3.0, and 3.5 kg/s. The generator is equipped with a brake that engages gradually if it operates above its intended speed (i.e. the generator protects itself from damage by partially engaging a brake when mass flow is greater than 3 kg/s and fully engaging the brake when mass flow is 5 kg/s or greater). The efficiency of the generator system can be estimated using the graph on the next page. Assume no losses due to friction in the pipes. Efficiency of Generator vs Mass Flow Rate 0.8 0.7 0.6 0.5 0.4 0.3 0.2 Water Tank 0.1 1. 2 6. Mass Flow Rate (kg/s) Generator A= 25 cm? Efficiency
