2. Air at 40 °C and 1 atm (abs) flows over a sharp edged flat plate with L = 4 m, a width of 6 m and U» = 1.8 m/s. For one side of the plate, find: (a) (i) The local boundary layer thickness 8(L). (ii) Local skin friction coefficient at x = L, Cr (L). (iii) Local wall shear stress at x = L, tw(L). (iv) Drag coefficient over the total plate and Drag force over the total plate. (b) A polymer solution (density = 1180 kg/m³) is being pumped at a rate of 4200 kg/h through an 80 mm inside diameter pipe. The flow is known to be laminar and the power-law constants for the solution are m = 3.6 Pa.s (N.s/m²) and n = 0.8. (i) Estimate the pressure drop over a 30 m length of straight pipe (ii) Estimate the centre-line velocity. (iii) Calculate the Reynolds number.
