Energy balance

$2000$ kg$/$h of a fruit drink $(25$deg C and $11$deg Brix$)$ is being concentrated to $40$deg Brix in a single effect evaporator operating at a vacuum level sufficient to cause the water to evaporate at $75$deg C $.$ As a heating medium, steam is injected at $200$ kPa $($Quality: $50\%)$ which comes out as condensate at $75$deg C$.$ Energy losses through the evaporator walls are minimal $345$ kJ$/$h$.$ Calculate the flow of all process streams and the steam economy. The Cp of the original and concentrated fruit drink are: $5\mathrm{.}3$ and $4\mathrm{.}1$ kJ$/$kg C$.$

$1.$ Build$/$create a flow chart with symbols and clear nomenclature

$2.$Generate the material and energy balance equations around the process.

$3.$Determine the enthalpic content of each stream. Reference state: water at $0$deg C$.$

$4.$ Solution of the energy balance, and calculation of the flow and the steam economy.
