In a confectionery company, with separate streams, sugar, oil, corn syrup, cocoa, vanilla extract and milk enter a mixer-kettle and exit the boiler as soft confection. Sugar (sucrose, C12H22O11) is obtained from a sugar farmer who previously worked as a chemist. The farmer packages the sugar in lbmol, and the sugar is used at a rate of 1.75 lbmol / hr in the production process. The oil is fed into the process at a rate of 60 lbm / hr, corn syrup at a speed of 3.5 gal / hr, and cocoa at a rate of 17lbm / hr. Finally, the vanilla extract is fed at a rate of 1 lbm of vanilla extract per 30 lbm of sugar. (Assume that the densities of corn syrup and milk are equal and 62.4 lbm / ft3.) a. How many gallons of milk per hour should be fed into the process for a total of 830lbm / h of confectionery production? b. Calculate weight fractions of components in input current
