What is steady flow energy equation for nozzle?
h1−Q=h2h1−Q=h2 Where Q = Heat lost by 1 Kg of steam passing through the condenser. Nozzle: In case of a nozzle as the enthalpy of the fluid decreases and pressure drops simultaneously the flow of fluid is accelerated.
What is the steady flow energy equation for a boiler?
[Solved] The steady flow energy equation: Q = m(h2 – h1) is app.
What is steady flow energy equation in thermodynamics?
The steady flow energy equation tells us that if there is no heat or shaft work (the case for our adiabatic inlet) the stagnation enthalpy (and thus stagnation temperature for constant Cp) remains unchanged.
Is nozzle steady flow?
Nozzle. A nozzle is a steady state steady flow device to create a high velocity fluid stream at the expense of its pressure. Usually, the process through the nozzle is treated as adiabatic. Since there are no moving parts, shaft work is zero.
What is a nozzle?
A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas).
What is flow work derive the equation of flow work?
The work done in pushing the fluid is: Wflow = F.s = PA. s = PV (kJ) or in a unit basis, wflow = Wflow / m = Pv (kJ/kg) Note that the flow work is expressed in terms of properties. The flow work can also be written as a rate equation.
What is the steady flow energy equation for compressor?
If the control volume is well insulated (i.e. adiabatic), then, q = 0. For steady flow devices, such as turbines, compressors and pumps, is power transmitted through a shaft. The unit of ke is m2/s2 which is equivalent to Joule/kg. The enthalpy is usually given in kJ/kg.
How do you calculate energy flow?
s = PV (kJ) or in a unit basis, wflow = Wflow / m = Pv (kJ/kg) Note that the flow work is expressed in terms of properties. The flow work can also be written as a rate equation. The property θ is called methalpy.
