Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Pressure Drop of Power-Law Fluid in Laminar FlowA power-law fluid having a density of 1041 kg/m3 is flowing through 14.9 m of a tubing with an inside diameter of 0.0524 m at an average velocity of 0.0728 m/s. The rheological or flow properties of the fluid are K′ = 15.23N·sn′/m2 (0.318 lbf·sn′/ft2) and n′ = 0.40. Calculate the pressure drop and friction loss using Eq. (9.1-10) for laminar flow. Check the generalized Reynolds number to make sure that the flow is laminar. Repeat part (a) but use the friction-factor method

Water to a residential area is transported at a rate of 1.5 m3/s via 70-cm-internal-diameter concrete pipes with a surface roughness of 3 mm and a total length of 1500 m. In order to reduce pumping power requirements, it is proposed to line the interior surfaces of the concrete pipe with 2-cmthick petroleum-based lining that has a surface roughness thickness of 0.04 mm. There is a concern that the reduction of pipe diameter to 66 cm and the increase in average velocity may offset any gains. Taking ? = 1000 kg/m3 and ? =1× 10−6 m2/s for water, determine the percent increase or decrease in the pumping power requirements due to pipe frictional losses as a result of lining the concrete pipes.
