Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.

2. 2 kg of water in a piston-cylinder assembly undergoes two consecutive reversible processes: a. Process 1-2: Isentropic compression from P1 = 0.1 MPa, T1=100°C to P2=D0.5 MPa b. Process 2-3: Isobaric process to a temperature T3 = 400 C Determine heat transfer (kJ), work (kJ), and change in specific entropy (kJ/kgK) for each process.
A piston-cylinder device initially contains CO2 at 200 kPa and 400°C and the total enclosed volume is 300 litres. Due to heat loss, the piston moves downwards to a position where it sits on a pair of stoppers and its final enclosed volume is 150 litres. Further heat loss leads to the pressure being reduced to 160kPa. Workout 1) the final temperature, 2) the total work done by CO2 and 3) the total heat transferred to CO2. Also make some comments on the result of heat and create a schematic p-v diagram of the process. The following assumptions are to be made: CO2 is a perfect gas and its molecular mass is 44kg/kmol. The ratio of specific heat capacities, γ (gamma) is 1.3 The volume occupied by the stoppers is to be ignored. There is no leakage in the system There is no friction between the cylinder and piston walls and the piston moved slowly at the same speed therefore, no acceleration.

Problem 4 A 0.15-m rigid tank initially contains R-134a as saturated vapor R-134a at 0.6 MPa. The tank is connected by a valve to a supply line that carries R-134a at 1 MPa and 26°C. The valve is now opened, allowing the refrigerant to enter the tank, and is closed when it is observed that the tank contains only saturated liquid at 0.8 MPa.

A 100L tank initially contains water at 100kPa and a quality of 1%. Heat is transferred to the water, raising the temperature and pressure. At a pressure of 3 MPa, a safety valve opens and saturated vapor at 3 MPa flows out. The process continues, maintaining 3 MPa inside until the quality in the tank is 90% and then stops. Determine the total mass of water that flowed out and the total heat transfer.
1. Steam at a pressure of 2MPA and temperature 300°C is passed at a constant rate into a desuperheater unit. The desuperheater is accomplished by continuously spraying water at 95 °C onto incoming superheated steam. The amount of water injected is so regulated that both the water and superheated steam finally change into dry steam at 2 MPa. If the resulting mixture of dry saturated steam leaves the desuperheater at 2MPA and the rate of I kg/s, find the mass of superheated steam used per hour and the mass of water to be injected per hour. Fond also the diameter of the pipe through which the superheated steam flows to the superheater if the speed of the steam through the pipe is not to exceed 25m/s..
