How to gas can follow several different paths as it expands from state 1 to state 2. In general, each path will have a different area underneath it, and since this area represents the magnitude of the work.

This is a repeated question. I have asked this question but it was rejected. I am submitting the problems to check my understanding. I completed the problems already and I am not being graded on them. If you are able to, please state your assumptions and table.

Q2: A U-shaped tube is closed at one end; the other end is open to the atmosphere. Water fills the side of the tube that includes the closed end, while oil, floating on the water, fills the side of the tube open to the atmosphere. The two liquids do not mix. The height of the oil above the point where the two liquids touch is 75 cm, while the height of the closed end of the tube above this point is 25 cm. What is the gauge pressure at the = 1000 kg/m³ and Po = 900 kg/m³ ) 3 3 closed end? (ew = Solution: -Po h=75 cm P3 %3D d= 25 cm Pi Pw

Describe a closed system with a moving boundary?

A closed system loses energy by heat transfer at the rate of 10kJ/s. Write the energy balance for this problem if the system operates at steady state

Let's compute how much energy it takes to make a cup of coffee or tea. Eight ounces of water has a mass of about 0.22 kilograms. How much heat must be transferred to the water to raise its temperature from 20°C to the boiling point, 100 C?

Spring is hung vertically, and an object of mass (m) is attached to its lower end. The spring stretches a distance (d) from its equilibrium position-How much work is done by the spring on the object as it stretches through this distance?

A. Find the specific volume and quality of water at 50kPa and 190 degree Celsius. B. Find the specific volume and quality of water at 50kPa and 30 degree Celsius.
