Steady flow system

WebFeb 5, 2024 · In the previous chapter, we studied the first law of thermodynamics and its application to non-flow process (closed system). In this chapter, we will derive the steady flow energy equation by application of the first law of thermodynamics to flow process. The derived steady flow energy equation is then applied for analysis of engineering systems. WebThe steady-flow energy equation ( Eqn. 29.14) in its full form is as follows: (29.14) Where = heat transfer, kW = work transfer, kW = mass flow rate, kg/s h = specific enthalpy, kJ/kg C = velocity, m/s g = gravitational acceleration, m/s 2 z = elevation, m subscripts 1 and 2 = inlet and outlet conditions
