Possible assumptions to be made is the following:

1.)No BPR (Ivermectin)
2.)A1 = A2
3.)Specific heat capacity is kept constant at 4 kJ/kg-K

Also, please include the steps on did you solve for this. For example, step 1:, step 2:, step 3 and so on.

Problem A pharmaceutical company wants to concentrate an Ivermectin solution to 50%. It was fed at a relatively low viscosity at 2.5 kg/s 15% wt. basis. The feed temperature is 25C and the specific heat capacity is kept constant at 4 kJ/kg-K. There are possible combinations of the operation that can be conducted and the table below shows the options of the company. For Single-Effect Operation Steam Conditions Saturated at 18 psia 18 psia, 390 K, condenses at 389 K, saturated Vapor Chest Conditions Saturated at 17.91 psia 17.91 psia, 382 K
