Derive Steady Flow Energy Equation
It is also more convenient to divide the work into two terms. 1 the flow work done by the system which is p 2 v 2 -p 1 v 1 and 2 any additional work which we will term external work or shaft work w s.
Engineering Thermodynamics Steady Flow Energy Equation S F E E
Short Video on derivation of Steady Flow Energy Equation SFEE for Nozzle.
. Solution for Derive the Steady Flow Energy Equation from the first law of thermodynamics. Let us implement above data that we have mentioned above in steady flow energy equation for a steady flow process and we will have following equation H 1 - W H 2 We have taken work energy as positive because turbine is producing the work energy and this work is being done over the surrounding by the system. We will call this the steady flow.
The relation 313 is known as the steady-flow energy equation. Mass flow rate in m1 Mass flow rate out m2 constant m. 1 the flow work done by the system which is p 2 v 2 -p 1 v 1 and 2 any additional work which we will term external work or shaft work w s.
State any assumptions made. Here are the links for various videos related to SFEEGeneral form of Steady Flow. Starting from the steady flow energy equation derive the appropriate equations for work done by the turbine and work done on the compressor.
Energy basis equation and Mass Basis Equ. δW p2A2δs2 p1A1δs1. It is also more convenient to divide the work into two terms.
We will call this the steady flow. Volume flow rate A m2 C ms. Substitution into eqn 312 now yields δQ δm where q represents the net heat transferred to the fluid divided by mass and w represents the net shaft work done by the fluid divided by mass.
B Again using first principles show how the energy equation would change for the case when the system is unsteady. I am trying to learn this for upcoming exams. In addition what is flow energy.
Consider the flow of fluid through a pipe of cross sectional area A specific volume V at Velocity C. It consist of both equations ie. But i can find nowhere on line which breaks down this sort of question.
The given information is summarized in the table below for three different cases Given Parameters Case A Case B Case C Power delivered by the 20 kW 25 kW 30 kW electric motor into the compressor Mass flow rate of the air 03 kg 05 kg 1 kg drawn. This video will derive SFEE - Steady Flow Energy Equation Derivation by using simple steps. Starting from the steady flow energy equation derive the appropriate equations for work done by the turbine and work done on the compressor.
Do you think that fluids at rest. Steady Flow System - Defined as the system in which the mass flow rate into the system is equal to mass flow rate out of the system. This video is regarding derivation of General Form of Steady Flow Energy Equation.
Mechanical Engineering questions and answers. Use the summation of energies. The total work done by the fluid considered is therefore.
We will call this the steady flow. Get complete concept after watching this videoTopics. A Given the system shown in the figure below derive the steady flow energy equation from first principle.
It is also more convenient to divide the work into two terms. Derive the Steady Flow Energy Equation from the first principles. Short Video on Steady Flow Energy Equation SFEE for Steam Condenser or Condenser.
1 the flow work done by the system which is p 2 v 2 -p 1 v 1 and 2 any additional work which we will term external work or shaft work w s. State any assumptions made. Derive the Steady Flow Energy Equation from first principles Hint.
