A turbo feed pump requires driving saturated water from the condenser into the boiler. The condenser pressure is 0.1 bar and the boiler pressure is 100 bar. The required feed water flow to the boiler is 0.2 m3 / sec and in the drive process the water increases its temperature by 2° C. The inlet pipe to the pump has a diameter of 60 cm and at the discharge it is 35 cm. On the drive side of the turbo pump, it has saturated steam at 25 bar at the inlet and at the discharge it has a pressure of 0.1 bar and a quality of 0.65. Determine: a) The mass flow of feed to the boiler b) The real power of the turbo pump assuming an efficiency of 90% in the water delivery c) The mass flow of steam through the turbo pump, for this calculation, neglect the effect of speeds. d) Steam velocity in the supply pipe to the turbo pump if it has a diameter of 30 cm.
