water is heated from 15°C to 50°C passing through a tube of 2.5 cm diameter. The velocity of water is 1.2 m/min, the outer surface of tube is heated by an electric heater providing uniform heat flux of 15 kW/m². Find out a) The length of tube required. b) Tube surface temperature at the exit. Take the following properties of water at average temperature of 33°C: p=995 kg/m³, Cp = 4.175 kJ/kg. °C, k = 0.615 W/m. °C.08 × 10³ N s/m²
