1. Hot water is to be used to leach a protein out of seaweed in an isothermal multistage crosscurrent system.

The seaweed slurry, consisting of 48.1% solids, 2.9% protein, and 49% water, enters at a rate 400 kg/h. The hot water is fed at rate 500 kg/h. How many ideal stages required if It is desired to have the outlet underflow have a maximum residual concentration of 0.2% protein on a solid-free basis. 2. Hot water is to be used to leach a protein out of seaweed in an isothermal multistage countercurrent system. The seaweed slurry, consisting of 48.1% solids, 2.9% protein, and 49% water, enters at a rate 400 kg/h. The hot water is fed at rate 500 kg/h. How many ideal stages required if It is desired to have the outlet underflow have a maximum residual concentration of 0.2% protein.
