Refrigerant $134$ a is the working fluid in a geothermal power plant operating on a Rankine cycle. Saturated vapor at $63C$ enters the turbine, and condenser operates at a pressure of $6$ bar $.$ The rate of energy input from geothermal flow is $(0\mathrm{.}8+{0\mathrm{.}01}^{**}(A))kW$ per $m^3.$ Determine the minimum possible geothermal flow rate in $\frac{m^3}{sec}$ for the power developed by the plant, AND THE INTERPOLATION is NECESSARY.
