A feed containing 3% by weight sugar is fed to a double-acting feedback evaporator. The feed enters the system at 45C and is concentrated to a sugar content of 25% by weight. The boiling point elevation of the solution is considered to be negligible. Each effect has a surface area of 93 m2 and the collective heat transfer coefficients are U1= 2835.3 W/m2K and U2=3969.4 W/m2K. At an absolute pressure of 689.3 kPa, saturated steam is fed to the first effect as the heating medium and the evaporation absolute pressure in the second effect is 6.75 kPa. The heat capacity of all solutions is considered equal to the heat capacity of water. Calculate the feed flow rate (kg/h) and the flow rate (kg/h) of the product containing 25% KM. Note: Write clearly all the operations you have done in solving the problem and schematize the system.
