An isentropic process is a process in which the entropy remains constant. In this process, the initial (s1) and final (s2) entropies of the system are equal: (7.24)s1=s2 Engineering systems or devices such as pumps, turbines, nozzles, and diffusers essentially operate without exchanging ...
Since this is an open system, the energy rate balance for a steady state, steady flow, single-inlet, single-outlet system is (neglecting kinetic and potential energy effects) ERB (SS, SF, SI, SO) Q˙−W˙+m˙m(hm1−hm2)=0and, since an isentropic process is normally also...
Hugoniots for graphite and diamond have been calculated. Numerical simulation data for the graphite–diamond transition in the isentropic compression process using a metallic z -pinch with diamond saving have been reported.doi:10.1134/S1063784217050231V. V. Prut...
When there is no heat transfer occurring between a given system and its environment, a process known as adiabatic takes place. WithQ=0, the first law of thermodynamics reduces to Answer and Explanation:1 Isentropic process is a type of adiabatic process which is reversible. This type of proces...
The correct Answer is:−γ To solve the problem, we need to find the value of b for which the specific heat capacity in the process is zero. We start with the given relationship between pressure p and volume V: p=aVb Step 1: Understand the condition for zero specific heat capacityThe...
aIn this model, it is assumed that during the vaporization process, only a fraction y of the fluid is transformed into saturated mixture, the other fraction (1-y) remains metastable liquid and is submitted to an isentropic evolution. 在这个模型,它假设,在汽化过程期间,只有流体的分数y被变换成...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
This inherent effect ('seeded beam effect') of the isentropic expansion of the gas from atmospheric pressure into vacuum, may result in an over- or under- estimation of ratios of ion signals obtained from measurements performed at a fixed pass energy set in the energy analyzer. However, this...
Therefore, the isentropic pressure is always taken to be equal to the actual pressure at the exit of an isentropic process, and the isentropic pressure ratio is always the same as the actual pressure ratio for these systems. The equation for the thermal efficiency of the Carnot cold ASC can ...
and, since an isentropic process is normally also adiabatic, W˙/m˙m=hm1−hm2=cpm(Tm1−Tm2) For an ideal gas in an isentropic process, Eq. (7.38) gives Tm2=Tm1(pm2/pm1)(km−1)/kmand, using the results of Example 12.4, this gives Tm2=(20.0+273.15 K)(1.08/0.101)0.66/...
