In addition to the physical data the things I’d like you to consider are: Longest dippipe we could have without internal vessel modifications (to add supports etc..) Mechanical design for a directional dip-pipe to direct recirculation to the vessel wall , and if this is ok for stress/erosion risk on the vessel wall given the high recirculation flow rates Vessel fabrication drawings will be provided Nozzle will be used for the dip-pipe Vessel data sheet will be provided with process an...

I have five high-school level physics assignments hosted on the Gizmos platform. I will share a Google Doc for each assignment that already contains every question and the step-by-step instructions I need you to follow. All I need back is the same Doc filled in with clear, fully worked answers; no separate reports or uploads are necessary. Gizmos restricts access to users inside the United States, so you must be physically located in the U.S. (a standard VPN will not pass their geo-check). Once you confirm that requirement, you will receive the classroom login and immediate access to all five activities. Deliverables • Completed Google Doc for each of the five assignments, showing your reasoning and final answers. Acceptance I will review each Doc in Gizmos’ teacher view;...

I need a fresh set of problem-solving questions that I can drop straight into an assessment for my Chemical Engineering Thermodynamics course. The focus is thermodynamic cycles only—Rankine, Brayton, refrigeration, combined cycles, the works—nothing on phase diagrams or heat-transfer calculations. Each question has to challenge an advanced undergraduate, so assume they already know the First and Second Laws, can read property tables, and are comfortable with ideal-gas and real-fluid analyses. Numerical answers must be attainable without exotic software; standard steam tables, refrigerant charts, or an EoS such as Peng–Robinson are fine. Deliverables • 8–10 original problems written in clear, exam-ready wording • Fully worked step-by-step solutions,...
