The inner wall of a pipe is cooled by forced convection by a flow of water in the pipe. The pipe is 300 m long and the wall surface temperature is 82°C. The flow in the pipe is turbulent and measured at a speed of 3 m/s on a pipe with a diameter of 25 mm. If water enters and leaves at temperatures 21°C and 54°C, determine the convection heat transfer coefficient by the equation (a) Dittus Boelter, (b) Colburn and (c) Sieder-Tate
