I need the answer as soon as possible

2. (30) Water flows in a 3-cm dia long tube so that the Reynolds Number based up on the diameter is 1350 (laminar flow). The average bulk temperature is 35 C. The temperature and velocity profiles are fully developed. Take the properties of water at the bulk temperature. (a) Calculate the maximum velocity of water in the tube. What would be the heat transfer coefficient if the tube wall had (b) constant heat flux (c) constant wall temperature
