Answer:
The temperature of the strip as it exits the furnace is 819.15 °C
Explanation:
The characteristic length of the strip is given by;
The Biot number is given as;
< 0.1, thus apply lumped system approximation to determine the constant time for the process;
The time for the heating process is given as;
Apply the lumped system approximation relation to determine the temperature of the strip as it exits the furnace;
Therefore, the temperature of the strip as it exits the furnace is 819.15 °C
Answer:
Explanation:
The turbine is modelled after the First Law of Thermodynamics:
The work done by the turbine is:
The properties of the water are obtained from property tables:
Inlet (Superheated Steam)
Outlet (Superheated Steam)
The work output is:
