(5) Through the pipeline with an inner diameter of 32 mm water is flowing with average velocity of 1,2 m/s. Calculate the heat transfer coefficient from the liquid to the pipe wall, assuming that the average temperature of water is 30°C. How change heat transfer coefficient when the liquid velocity increases two times, and the average temperature will be than 60°C.

Question
(5) Through the pipeline with an inner diameter of 32 mm water is flowing with average
velocity of 1,2 m/s. Calculate the heat transfer coefficient from the liquid to the pipe
wall, assuming that the average temperature of water is 30°C. How change heat
transfer coefficient when the liquid velocity increases two times, and the average
temperature will be than 60°C.
(6) Assuming that the average water flow velocity is 1,2 m/s, to determine how will
change the result corresponding to Exercise (5), if the pipe cross section would be
a square.
