What does it mean for an engineering device that has steady-flow? (choose 3 answers) 1- it has been operating for a long time. 2- the properties do not change with time. 3- the property values can be different at different location in the device. 4- the total energy content in the control volume remains unchanged. 5- the rate of energy coming into the system equals to the rate of energy exits the system.

1. The pressure in the substance drastically decrease from 354 to 21 POUNDS PER SQUARE INCHES (PSI), the heat energy of the open system reduces 555BTU/LB, and the volume increases from 1 to 10FT^3/LB. a.) Determine the work per LB. Units:BTU/LB b.) Determine the work in HP (Horse Power) for 10LB per min. (1HP = 42.4BTU/MIN) Units: HP
When a stationary mass of gas was compressed without friction at constant pressure its initial state of 0.8 m3 and 0.105 MPa was found to change to final state of 0.40 m3 and 0.105 MPa. There was a transfer of 85 kJ of heat from the gas during the process.How much did the internal energy of the gas change ? * 1 Add File
Thermodynamics deals with forms of energy and change in the total energy of a system which can be assigned a value of zero at some reference point. The total energy of a system has two groups: macroscopic and microscopic. Describe the concept of macroscopic and microscopic forms of energy in a thermodynamics system. (d) A quantity of matter or a region in space chosen for study is referred to system. Some thermodynamics relations that are applicable to closed and open systems are different. It is extremely important to recognize the system before start analyzing it. Thus, differentiate among following thermodynamics systems. (i) Isolated system; (ii) Rigid system; and (iii) Adiabatic system.

Task 1 You are a student at the HTU University, the instructor of the fundamental of thermodynamic course asked you to explain the fundamentals of thermodynamic systems to Grade 10 school students to help them visualize the importance of thermodynamics in their life starting from their car engine and moving to the different appliance that they use in their home, discuss the following with school students: Q1. What does thermodynamics mean and represent? Give examples from your daily life. Q2. What is a thermodynamic property? What is the difference between intensive and extensive properties. Why the density is an intensive property; it is dependent on mass and volume which are extensive properties, right?. Q3. What is the difference between energy and heat transfer? Give examples on both. Q4. What does the first law of thermodynamics state? Give two examples on the first law of thermodynamics from your daily life. Q5. Write down the equation of energy balance for closed, open, and…
