Each pressure vessel in a proposed design for the desalinization of seawater is rated for $35\%$ recovery at flow rates between $850$ to $1,300$ m$3/$day$.$ An array system must yield $2,000$ m$3/$d of pure water for a town of $5,000$ people at a permeate recovery of $50\%.$ Verify whether a $4$x$2$ array system with Qf $=4000$ m$3/$day will work for this town.
