Water at a temperature of 35 °C is flowing steadily in a 2.5 mm diameter, 15-meter long tube at an average velocity of 0.60 m/sec. The cross-section is circular and the material is perfectly smooth. The flow can be considered fully developed. Find the following quantities:a. The Reynolds number. State whether the flow is expected to be laminar or turbulent. (Check your math if you get a Reynolds number in the turbulent range.)b. The Darcy friction factor, ?.c. The pressure drop over the length of the tubing, Δ?, and the corresponding head loss, ℎ?.
A series of 10 chips are placed on an insulating substrate as shown in the figure. Each chip has a length (Lc) of 15 mm, it is 20 mm wide and 10 mm thick. Upstream of the chips there is an input length (Le) of 15 mm. Whether each chip should dissipate 0.5 W and stay at a maximum temperature of 80 °C, what should be the speed uꝏ that the ambient air at 25 °C should be blown so that this condition is met? The emissivity of the chips is 0.8. consider that the chips do not exchange heat with each other and there is a turbulence generator upstream of the plate.
Air that is fully-developed flows in a rectangular duct of inside dimensions 0.610 m x 0.305 m. The inlet air temperature is 21.1°C, and at outlet the air temperature is 26.7°C.

Also, solve for (c) h and (d) Ts,i.
A tube bank uses an aligned arrangement of 15‐mm‐diameter tubes with ST=SL=30 mm. There are 10 rows of tubes with 50 tubes in each row.
