$3)$ A tomato$-$juice enters an evaporator at the rate of $1200$kg $/$ h at $10$ deg $*$ C Evaporation takes place at $10$ kpa and $45\mathrm{.}81$ deg $*$ C The concentrated juice contains $35\%$ of solids and the hourly rate of removal of water vapor $($as saturated vapor state at $10$ kPa and $45\mathrm{.}81\backslash$deg C$)$ is $960$ kg$.$ The steam is used for evaporation and enters the evaporator as saturated vapor state at $10$ kPa and leaves as saturated liquid at $10$ kPa. The steam used for heating in the evaporator doesn't mix with the tomato$-$juice. Assume no heat losses in the system a$)$ calculate $\%$ water in the tomato juice entering the evaporator b$)$ calculate the quantity of steam needed per hour for heating. c$)$ What do you recommend to increase the amount of removal of water vapor from the evapoart
