A water-tube steam generator operating at (160 bar) has (15 m) high and (75 mm) I.D. tubes. Assuming saturated water in the downcomer, a water-steam mixture in the tubes with an average density of (288.33 kg/m³), and an inlet tube velocity of (0.92 m/s). Calculate the pump pressure necessary for the given flow. Also, calculate the mass flow rate through the downcomer.
