Can steam power plant work with a compressor instead of condenser and heat pump?

Steam power plant cannot work by replacing condenser and heat pump with a compressor this is because at the outlet of turbine there would be a mixture of steam and water and there is no device which can move a mixture of steam and water from one place to another at same time so either first we have to convert the mixture in vapor state or liquid state. So here in this case mixture is completely converted into water and then pumped to boiler. 

FLUID DENSITY DEPENDANCE MORE ON TEMPRATURE THAN PRESSURE

Density of fluid depends more on temperature than pressure. Mathematical reason is co-efficient of volume of thermal expansion
above equation shows that changing temperature would cause greater volume change and consequently density would be more affected by temperature.
Physical reason is that by changing pressure volume change takes place in one dimension whereas changing temperature would cause volume change in all 3 directions.

ATOMIC SIZES

ATOMIC SIZES:-

    Size of an atom is very important in determining its properties whether physical or chemical properties. Atoms are assumed to be spherical so radii is used to determine there sizes. There are various radii to determine size of an atom depending upon type of compound.
