A)Whick correlation should be considered for the calculation of the heat transfer coefficient on the inner side of the tube?

B)Calculate the mean bulk temperature in C.

C)If the heat transfer coefficient is 2500 W/m^2-K, calculate the total heat transfer in kW.

- Which correlation should be considered for the calculation of the heat transfer coefficient on the inner side of the tube? A heat exchanger tube made of carbon steel (k=46W/mK) with a diameter of 1 inch (14 BWG) (outer diameter: 25.4mm, inner diameter: 21.18mm, wall thickness: 2.11mm ) is used for water flow at a velocity of 0.6m/s. The length of the tube is 5.2m. The water enters the tube at a temperature of 25C and exits at a temperature of 45C. Steam condenses on the outer surface of the tube, and the inner wall temperature of the tube is assumed constant at 60C
