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.

! 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. (You must provide an answer before moving to the next part) The final temperature is The final pressure is °C. kPa.

NOTE: Complete solution and show the derivation/cancellation of units. A steel flask of 0.04 m capacity is used to store Nitrogen at 120 bar and 20°C. The flask is protected against excessive pressure by a fusible plug which will melt and allow the gas to escape if the temperature is too high. A. How many kilogram of Nitrogen will the flask hold at the design conditions? B. At what temperature in °C must fusible plug melt in order to limit the pressure of flask to a maximum of 150 bar?
As shown in the figure below, a cylinder fitted with a piston is filled with 600 lb of saturated liquid ammonia at 45°F. The piston weighs 1 ton and has a diameter of 2.5 ft. * Your answer is incorrect. V= What is the volume occupied by the ammonia, in ft3? Ignoring friction, determine the force required, in lbf, by mechanical attachments, such as stops, to hold the piston in place. What is the volume occupied by the ammonia, in ft³? i 15376500 Patm = 1 atm Piston ft3 Ammonia Saturated liquid - Weight = 1 ton D=2.5 ft
Air as an ideal gas is contained in a piston/cylinder system constrained by a non-linear spring. Initially the gas in the cylinder is at 100 kPa, which is balanced by the atmospheric pressure outside of the cylinder (the weight of the piston is negligible). The force on the spring at the start is zero. The spring force is F=kx². k=600. kNt/m². The cross-sectional area of the piston is 1 m², the initial volume is 1 m³, and the initial temperature is 300 K. Heat is added until the volume of the gas has expanded to 1.5 m³. Find: (a) The work done by the gas on the face of the piston (kJ). (b) The final temperature (K). (c) The amount of heat added (kJ). Hint: This problem is easiest if you calculate the spring work and the atmospheric work separately. Air V₁=1.0 m³ Piston Area = 1.0 m² T₁=300 K P₁=100 kPa Atmospheric P on upper piston face= 100 kPa
