Resume Pertemuan 1

pada pertemuan ini kita membahas tentang consiousnes bagaimana cara menghubungkan metode numerik dengan ketuhanan yang maha esa. disini juga diperkenalkan dengan sistem dari air.eng.ui.ac.id. kami melakukan diskusi tentang kita itu harus consiousnes terhadap apa yang kita lakukan ntah itu dalam belajar metode numerik maupun mata kuliah lain. Kita juga membicarakan apakah ketika meninggal diri kita ada atau tidak. kurang lebih ini adalah pertemuan pembukan yang meng introduce antara dosen dengan mahasiswa yang meng highligt=ht tentang consciouness.

Design & Optimization of Pressurized Hydrogen Storage

objective Design and Optimization

specification cap : 1 L Pressure Level : 8 bar

Maximal price Rp.500000

Answer To design and optimize a pressurized hydrogen storage system with a capacity of 1 liter and a pressure level of 8 bar within a maximum price of Rp. 500,000, we need to consider various factors such as the storage vessel, materials, safety, and cost-efficiency. To answer this i use ChatGPT to help answer and Here's a suggested approach to designing and optimizing such a system:

Storage Vessel Selection:

Choose a lightweight and compact storage vessel with a capacity of 1 liter and a working pressure rating of at least 10-12 bar to provide a safety margin. Consider materials such as carbon fiber reinforced composites or high-strength steel that can withstand the desired pressure and minimize weight. Ensure the storage vessel complies with relevant safety standards and regulations.

Pressure Regulation:

Include a pressure regulator or pressure relief valve to maintain the hydrogen pressure at a constant level, preventing over-pressurization. Optimize the pressure regulator design to ensure efficient and reliable pressure control.

Safety Considerations:

Incorporate safety features such as burst disks or pressure relief devices to prevent excessive pressure buildup and ensure the system can safely vent hydrogen in case of emergencies. Implement a robust leak detection system to monitor and detect any potential leaks in the storage system. Follow safety guidelines and standards for hydrogen storage and handling.

Cost Optimization:

Consider cost-effective materials and manufacturing processes while maintaining safety and performance requirements. Explore potential cost savings by leveraging economies of scale in manufacturing or utilizing standardized components. Optimize the system design to minimize material usage and reduce manufacturing complexity.

System Integration:

Ensure proper integration of the storage system with the overall hydrogen infrastructure, considering factors like refueling protocols and compatibility with hydrogen fuel cell systems or other hydrogen-consuming devices.

Cost Analysis:

Conduct a thorough cost analysis considering the selected storage vessel, components, materials, manufacturing, and any additional safety features. Optimize the design and manufacturing processes to meet the maximum price requirement of Rp. 500,000.

It's important to note that designing and optimizing a pressurized hydrogen storage system requires detailed engineering analysis and expertise. Working with professionals experienced in hydrogen storage and considering the latest industry standards and regulations is highly recommended to ensure safety, performance, and cost-effectiveness.
