Chapter 6, Problem 6.29CU

A cylinder-piston apparatus contains nitrogen initially at 20 bar, 107ºC and 0.3 m ^ 3. The piston moves with negligible friction until the pressure reaches 5 bar. The process can be described by the equation V = 0.4-0.05P where v is in m ^ 3 and P in bars. Calculate work and heat

​ 1. 0.1m3 of an ideal gas at 300 K and 1 bar is compressed adiabatically to 8 bar. It is then cooled at constant volume and further expanded isothermally so as to reach the condition from where it started. Determine the following with aid of a NEAT DIAGRAM a. Pressure at the end of constant volume cooling b. Change in internal energy during the constant volume process c. Net work done and heat transferred during the cycle. Assume, Cp = 14.3 kJ/kg K and Cv = 10.2 kJ/kg K.

Water with a quality of 50% is contained in a piston/cylinder arrangement at state 1. It is heated at constant pressure until it is superheated vapor, at state 2. At this point, the piston is locked in place and the water is heated further at constant volume until state 3. Draw this two-step process on a P-v diagram and on a T-s diagram.

A piston-cylindrical device contains 1 kg of air at a temperature of 300 K and a pressure of 100 kPa. Air is compressed to a state where the temperature is 460K and the pressure is 600KPa. during compression there is a heat transfer from the air to the surroundings equal to 20kj. Using the ideal gas model for air, determine the work during the process, in kJ.note: apply the first law of thermodynamics for closed systems. FOLLOW THE NEXT STEPS Step 1.

A spring-loaded piston-cylinder device contains m= 1kg of carbon dioxide. Initially, the spring has no force on the piston and P₁ = 500kPa, T₁=150K, V₁ = 0.1m³. 1 Heat is transferred to the gas, causing the piston to rise and to compress the spring. At the state 2, T₂=900K, V₂=0.3m³. The gas is an ideal gas. 2 (1)How to determine the pressure P at the state 2? 2 O A. O B. OC. O D.
