Q2. Water is heated while following through a 1.5cmx 3.5cm rectangular cross section tube at a velocity of 1.2 m/s. The entering temperature of the water is 40°C and the tube wall is maintained at 85 C. Determine the length of the tube required to raise the temperature of water to 70 C. If the pressure loss in the tube is registered to be 10KPa. find the required pumping power. The properties of water are: p=985.5 kg/m, Cp- 4.18kJ/Kg. v=0.517x10 m/s, k-0.654 W/mK and Pr-3.26.
