2. (25 pts) Engine oil flows with a velocity of 6 m/s over a flat plate having 1m length and 1 m width. The oil has a free stream temperature To= 80 °C and the plate surface temperature is maintained at Ts = 0 °C. a. Determine whether the flow over the plate transitions to turbulent regime. b. Calculate the average friction factor and the average heat transfer coefficient for the plate by using the appropriate correlations. c. Calculate the...

PROBLEM 3 (45 points) The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a parallel flow shell-and-tube heat exchanger consisting of a single shell and 1x10 tubes, each executing two passes. The inner diameter of tubes is D = 50 mm and its thickness is 5 mm (Do not ignore the thickness). The steam condenses on their outer surface. Thermal conductivity of the tube...

[10] Design Problem As shown in the figure below, a double-pipe parallel-flow heat exchanger is used to heat cold fluid which is water (Cp = 4180 J/(kg.K), p = 1000 kg/m) from 20°C to 80°C at a rate of 0.15 kg/s. The heating is to be accomplished by hot fluid, which is geothermal water (Cp = 4310 J/(kg.K), p = 1050 kg/m²) available at 130°C at a mass flow rate of 0.25 kg/s. The inner tube has an inner diameter...
