A condenser consists of several tubes. The outer diameter of each tube is 2 cm, and the thickness is 2 mm. It is designed to condense saturated steam that enters the condenser at the mass flow rate of 100 kg/s. The steam pressure is 10 kPa. There is 10% moisture in saturated steam. The inlet temperature of cooling water is 20°C, and the outlet temperature is 40°C. Water velocity 2 m/s. The overall heat transfer coefficient based on outer surface area is 3.5 kW/m².K. The heat capacity of water is 4.2 kJ/kg.K. Water density is 1000 kg/m². Find the number of tubes and the length of each tube.
