NON FLOW AND FLOW PROCESSES CLASS NOTES FOR ENGINEERING Both non flow & flow processes play an important role in thermodynamics. These are part of various thermodynamic cycles. Cycles are power producing & power consuming. 1. Non Flow Processes The boundary of a non-flow process can be fixed, moving or imaginary. These are compression…
THERMODYNAMIC PROCESSES MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS MCQ increases understanding and clarity. It helps in using the concepts in real life applications. 1. A vapor becomes a gas as long as degree of super heat is Firstly < 200C Secondly < 500C Thirdly <400C None Ans: (iv) 2. Which of…
SSTATES OF MATTER AND PHASE CHANGE PROCESSES Differentiate between the three states of matter Solids Liquids Gases Have fixed volume and fixed shape Have fixed volume But have variable shape Variable volume And variable shape What are the various types of phase changes? Five types of phase changes Phase change Name of Process Practical Application…
ISENTROPIC AND ADIABATIC PROCESSES CLASS NOTES Isentropic process has constant entropy. There is no loss. It is a theoretical process. There is an adiabatic process which is irreversible. There is heat addition. There is internal and external losses. ISEN-TROPIC PROCESS Heat exchange is zero. dq=0, Tds=0 s = entropy = constant There is no internal friction…
THERMODYNAMIC PROCESSES AND PROPERTIES CLASS NOTES Any thermodynamic system works on a closed repeatable cycle. Each cycle consists of four processes. In these processes, there is transfer of heat and work into the system or out of the system. Normally processes have one variable as constant. Adiabatic process in which there is no heat…
