Q 1: An aqueous salt solution enters a crystallizer operating at a steady state at 25°C. The feed temperature is 90°C and the salt concentration in the feed is 40 weight %. The salt crystallizes as a pentahydrate. The crystals and the mother liquor leave the crystallizer. The molecular weight of the anhydrous salt is 135. The solubility of the salt at 25°C is 20 weight %. The feed flowrate required for a production rate of 100 kg/s of the hydrated salt, rounded to the nearest integer, is ____________kg/s.
