One thousand liters of 85.0 wt% glycerol-15.0% water solution is to be diluted to 60.0% glycerol by adding a 35.0% solution pumped from a large storage tank through a 3.0-cm ID pipe at a steady rate. The pipe dischages at a point 8.0m higher than the liquid surface in the storage tank. The operation is carried out isothermally and takes 11.0 minutes to complete. The friction loss (F of Equation 7.7-2) is 40.0 J/kg. Calculate the final solution volume and the shaft work in kW that the pump must deliver, assuming that the surface of the stored solution and the pipe outlet are both at 1.00 atm. Data: PH,0 = 1.00 kg/L;Pgly = 1.26 kg/L Vfinal = i Ws i kW
