## Mechanical Engineering Project: Steam Engine Efficiency Analysis ### Overview You are part of a team that is completing a mechanical engineering project. Your team built a steam engine that takes in superheated steam at 270°C and discharges condensed steam from its cylinder at 50°C. Your team has measured its efficiency to be 30.0%. ### Questions 1. **Comparing Measured Efficiency with Maximum Possible Efficiency** * **Question**: How does this efficiency compare with the maximum possible efficiency for your engine? * **Formula**: \(\frac{ε_{steam engine}}{ε_{max}}\) * **Input Field**: (default value: 74%) * **Submit Button**: * **Submission Information**: - "You currently have 3 submissions for this question. Only 10 submissions are allowed." - "You can make 7 more submissions for this question." 2. **Calculating Heat Released to Surroundings** * **Question**: If the useful power output of the engine is known to be 200 kW, how much heat does the engine release to its surroundings in 1.00 h? * **Input Field**: (default value is a blank field) * **Submit Button**: * **Submission Information**: - "You currently have 1 submission for this question. Only 10 submissions are allowed." - "You can make 9 more submissions for this question." ### Graphs/Diagrams * There are no graphs or diagrams included in this exercise. ### Instructions To submit your answers, input the calculated values into the provided fields and click the "Submit" button. Pay attention to the number of submissions already made, as each question only allows for a maximum of 10 submissions. #### Note: Ensure your answers are accurate to minimize the number of submissions required. --- This portion of the website can help students understand how steam engine efficiency is determined and measures taken in real-world engineering scenarios to estimate performance.
