The steady flow energy equation is written as
or,in the easy way the equations becomes
and with the flow rate,the equation may be written as
- In Boiler
In a boiler operating under steady conditions,water is pumped into the boiler along the feed line at the same rate as which steam leaves the boiler along the steam main, and heat energy is supplied from the furnace at a steady rate.
- In Condensers
If the condenser is in a steady state then the amount of liquid,usually called condensate,leaving the condenser must be equal to the amount of vapour entering the condenser.
- In Turbine
A turbine is a device which uses a pressure drop to produce work energy which is used to drive an external load.
- In Nozzle
A nozzle utilises a pressure drop to produce an increase in the kinetic energy of the fluid.
A throttling process is one in which the fluid is made to flow through a restriction, e.g. a partially opened valve or orifice,causing a considerable drop in the pressure of the fluid.
- In Pump
In applying the steady flow energy equation to a pump,exactly the same arguments are used as for turbine.
