A Rankine cycle power plant is being developed to operate an
irrigation system. In this power
plant solar energy will be used to boil a low boiling point fluid
within glazed flat plate solar
collectors. The working fluid that has been selected is the
commonly used refrigerant R 134a
(1, 1, 1, 2 tetrafluoroethane), tabulated properties of which may
be found in Tables A11, A12
and A13 at the rear of the prescribed text.
