Subcritical units operate below critical pressure and temperature, while supercritical units operate above critical pressure and temperature.
Subcritical units have lower efficiency and require more fuel compared to supercritical units.
Supercritical units have higher steam pressure and temperature, resulting in better efficiency and lower emissions.
Subcritical units are cheaper to build and maintain compared to supercri...
Water temperature changes to steam in water separator.
Water temperature decreases in water separator as steam is separated from it.
The separated steam has a higher temperature than the remaining water.
The temperature change depends on the pressure and flow rate of the water and steam.
The water temperature may drop by 10-20 degrees Celsius in the separator.
The steam temperature may increase by 10-20 degrees Celsius in t

Casting methods are processes used to create metal objects by pouring molten metal into a mold.
Sand casting: uses sand molds to create the shape of the object
Investment casting: uses wax patterns that are melted away to create the mold
Die casting: uses metal molds to create complex shapes with high accuracy
Permanent mold casting: uses reusable molds made of metal
Centrifugal casting: rotates the mold to distribute the m
Batch production is a manufacturing process where products are made in groups or batches, rather than individually.
Products are produced in specified quantities at a time
Each batch goes through the whole production process together
Common in industries like food processing, pharmaceuticals, and automotive manufacturing
Supercritical stage of steam refers to a state where it exhibits properties of both liquid and gas.
Occurs at temperatures and pressures above the critical point
Density and viscosity are similar to liquids, while diffusivity and compressibility are similar to gases
No distinct boundary between liquid and gas phases
Used in power plants for more efficient energy generation
