I get a little confused when it is stated "Flow rate is = Ma" Isnt flow rate= Av? ### Problem StatementA 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.### Diagram ExplanationThe diagram shows a setup with a water tank and a generator. Water flows from the tank to the generator, creating electrical output.- **Water Tank:** The tank provides water that flows through the generator.- **Generator:** Converts the kinetic energy of water into electrical energy. It is depicted in the system setup.- **Flow Path:** Water enters the generator through a pipe with a cross-sectional area of 25 cm².### Graph Explanation**Efficiency of Generator vs Mass Flow Rate**- **X-axis:** Mass Flow Rate (kg/s) ranging from 0 to 6 kg/s.- **Y-axis:** Efficiency ranging from 0 to 0.8.The graph shows the efficiency of the generator relative to different mass flow rates:- Efficiency increases linearly, peaking at around 0.75 at a flow rate of 3 kg/s.- Beyond 3 kg/s, efficiency decreases, reaching 0 when the mass flow rate is at 5 kg/s.### ApplicationUse the given information and diagram to calculate the electrical output based on the water level (h) for specified flow rates using the efficiency graph.
