One thousand liters of a 95 wt% glycerol-5% water solution is to be diluted to 60% glycerol by adding a 35% solution pumped from a large storage tank through a 5-cm ID pipe at a steady rate. The pipe discharges at a point 23 m higher than the liquid surface in the storage tank. The operation is carried out isothermally and takes 13 mm to complete. The friction loss (P of Equation 7.7-2) is 50 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 atm. Data. PH2O = 1.00 kg/

What is the order of the overall transfer function, G(s) = V(s)/U(s)? (b) What is the gain of G(s)? Under what condition(s) is the process gain negative?
Hydrogen chloride gas, produced by burning chlorine with hydrogen, is required at a supply pressure of 600 kN/m2, gauge. The pressure can be achieved by either operating the burner under pressure or by compressing the hydrogen chloride gas.
