Tips for asking Questions
- Provide any and all relevant background materials. Attach files if necessary to ensure your tutor has all necessary information to answer your question as completely as possible
- Set a compelling price: While our Tutors are eager to answer your questions, giving them a compelling price incentive speeds up the process by avoiding any unnecessary price negotiations
Sample Questions
- 1. Can you help me with this Thermodynamics question:
- A closed, rigid tank whose volume is 1.5 m3 contains refrigerant 134a, initially a two phase liquid-vapor mixture at 10C. The refrigerant is heated to a final state where temperature is 50C and quality is 100%. Locate the initial and final states on a sketch of the T-v digram. Determine the mass of vapor present at the initial and final state, each in kg.
- 2. Can you show me step-by-step how to determine the phase or phases in a system consisting of H2O at the following conditions and sketch p-v and T-v diagrams shown the locations of each state?:
- a) P= 80 lbf/in^2, T= 312.07 F
- b) T= 400 F, P= 360 lbf/in^2
