Example 4.3 On one side of a double pipe heat exchanger is saturated steam and water is flowing in the inner tube. The temperature of entering water is 20°C and the velocity of water is 1 m/s. The inner diameter of the inner pipe is 2.4 cm. Under steady conditions, determine the temperature of water at the length of 5 and 10 m from the inlet using the Runge-Kutta 4th order method. The total length of the heat exchanger is 10 m. Assume that the temperature does not change along the radius of the pipe. The density of water is 1000 kg/m³ and the specific heat capacity is 4184 J/kg K. The overall heat transfer coefficient based on the inside area is 200 W/m² K and the temperature of saturated steam is 250 °C. Check the answer by calculate the overall heat transfer coefficient

Question
Example 4.3 On one side of a double pipe heat exchanger is saturated steam and water is
flowing in the inner tube. The temperature of entering water is 20°C and the velocity of
water is 1 m/s. The inner diameter of the inner pipe is 2.4 cm. Under steady conditions,
determine the temperature of water at the length of 5 and 10 m from the inlet using the
Runge-Kutta 4th order method. The total length of the heat exchanger is 10 m. Assume that
the temperature does not change along the radius of the pipe. The density of water is 1000
kg/m² and the specific heat capacity is 4184 J/kg K. The overall heat transfer coefficient
based on the inside area is 200 W/ m² K and the temperature of saturated steam is 250 °
Check the answer by calculate the overall heat transfer coefficient
