OBJECTIVE: 1. To demonstrate the isentropic expansion process. INTRODUCTION: In thermodynamics‚ an isentropic process is one in which for purposes of engineering analysis and calculation‚ one may assume that the process takes place from initiation to completion without an increase or decrease in the entropy of the system .If a compression or expansion of a gas takes place with no flow of heat energy either into or out of the gas - the process is said to be isentropic or adiabatic. The isentropic

Hello city of Sparksville‚ I know you are all wondering what is going to be done about the outsourcing of jobs from the area. Without those jobs to help with the economy‚ the townspeople are suffering. That is why we have decided to look into some opportunities for Sparksville. Those opportunities include bringing a warehouse distributor business‚ a hybrid car business or an oil refinery to help the citizens of

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

determine the vapour pressure curve. Introduction Properties of a fluid can change when heat and work are applied to it. There’s an interchange between the fluid and its surroundings when heat and work are applied according to the study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas obeys the equation of state that the pressure‚ specific volume or density‚ and absolute temperature with mass of molecule and the gas constant

pump is switched off) and Pf is the final pressure (stabilized after valve opening). You will need to specify the absolute values at each pressure. Note that the equipment will measure the gauge pressure relative to atmospheric pressure. Therefore you will need to add the atmospheric pressure (take this value to be 100 kPa). Ensure you use a steady stable value for each pressure value. Plotting a graph of your data or analysing the data table should help you identify these values. You might consider

(rusting of iron‚ tarnishing silver) Also‚ almost all chemical reactions involve exchange of heat (or energy): in combustion reactions great deal of heat is released in neutralization reactions and others. Transfer of heat is a major theme of thermodynamics‚ the science of heat exchange (or energy exchange). Q: Why it is important to know the quantity of heat (energy) involved in a chemical reaction? Answer: when chemical reaction takes place the rearrangement of atoms takes place and
