Question

Consider liquid water flowing over a flat plate of length L = 1 m. The water has the following properties: ρ-1000 kg/m3, Cp-4000 J/kgK. 10 3 kg/ ms, k 0.6 W/m . C μ Midway through the plate at x = 0.5 m, you measure a heat flux to the surface of: 05 m 3181 W/m2 You also measure an average heat flux to the surface over the length of the plate of: "4500 W/m2 Knowing the latter, and knowing that the plate temperature is equal to 20° C do the following: a) Is the flow laminar or turbulent, or a mix of both? You must provide proof of this using the data provided. (b) What is the possible range of the freestream velocity U Ans 3·Tm = 20°C + 6。Cm 0.5s-0.5な0.5.
