A single effect evaporator is used to concentrate fruit juice from \( 5 \% \) to \( 20 \% \) solids. The diluted juice is fed into the evaporator at a temperature of \( 25{ }^{\circ} \mathrm{C} \) and a mass flow rate of \( 4720 \mathrm{~kg} / \mathrm{h} \). a) Draw a process flow diagram for the evaporator. b) Calculate the mass flow rate in \( \mathrm{kg} / \mathrm{h} \) of concentrated juice and vapour. c) Given that the steam used is \( 4300 \mathrm{~kg} / \mathrm{h} \), calculate the

Example: Let \( f(x)=\sqrt{x^{2}-3 x+2} \). Determine the domain of \( f(x) \)
