Water travels along a 3m long pipe of internal diameter 20mm at a rate of 30 kg per minute. The temperature at the entrance and exit of the pipe is 50°C and 30°C respectively. Determine: a) The rate of heat transfer from the water to the walls of the tube [3 marks] b) The Reynolds Number [3 marks] c) The Prandtl Number [3 marks] d) The Nusselt Number [4 marks] e) The Convective Heat Transfer Coefficient between the water and the wall of the tube [3 marks) f) The temperature of the wall of the pipe at the exit [5 marks] g) Comment on the flow regime in the pipe with regard to its suitability for heat transfer [4 marks] Total 25 marks
