Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

By actual measurement, the enthalpy of steam at 8 bar is found to be 3000 KJ/Kg. What is the quality of steam? If 500KJ/Kg of heat is added to this steam, what is the (i) Superheated temperature (ii) Degree of superheat (iii) Enthalpy of superheat?
4. One mole of helium gas is injected into each side of a slidable, airtight lead piston that separates two chambers of a sealed cylinder. The outside of the cylinder is insulated everywhere except where noted below. The cylinder and piston have lengths and cross- sectional area labeled in the diagram. The helium in the left chamber is heated from outside at a rate of 450 W, and the helium in the other chamber expels heat into a cool region. The full system eventually comes to steady-state. When it reaches steady state, the force needed to hold on the end cap is measured to be 18,000 N, and the piston has slid to an equilibrium point that is a distance à from the left end. force holding cap = 18,000N pressure. cross-sectional area of cylinder = 0.02m² x = ?

! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A piston-cylinder device initially contains 1 kg saturated liquid water at 200°C. Now heat is transferred to the water until the volume quadruples and the cylinder contains saturated vapor only. The saturated liquid properties of water at 200°C 3 are vf= 0.001157 m³/kg and uf- 850.46 kJ/kg (Table A-4). Water mkg 200°C Q Determine the final temperature and pressure.

N = 0 An insulated tank of volume 10+(10+N)/25 m and with a valve was filled with perfect tri- atomic gas at pressure 10 bar, where N is equal to the last two digitals in your student's ID number. Initially the valve was closed. A paddle wheel was mounted inside the tank and was run by 20 kW engine. The paddle wheel was turn on and at the same time the exit valve was opened. The gas temperature was constant though the whole process (due to very slow flow) and equal to 300 K. Calculate the time needed to decrease the pressure in the tank to 5 bar.
