3. a rankine vortex contains a viscous core surrounded by an irrotational free vortex. a piecewise equation for the velocity in a rankine vortex is uθ = γr/(2πr^2) for r ≤ r, and uθ = γ/(2πr) for r > r. ur = 0 everywhere.
a) compute the circulation around a circle of r ≤ r using the flow velocity.
b) compute the circulation around a circle of r ≤ r using the flow vorticity
c) compute the circulation around a circle of r > r using the flow velocity.
d) compute the circulation around a circle of r > r using the flow vorticity.

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?

Acantilever of 3 m length with a t-shaped cross-section is loaded by three concentrated loads: w,-80 n at the free end, w 30 n, and w,-60 n at a distance of 1 m from the free end. all loads are applied at the outer edges of the flange as indicated in the sketch below. (a)-determine the maximum torsional shear stresses in the flange and in the web at distances 0.5 m and 2.5 m from the free end (sections i and ii marked in the sketch) b)- determine thefh end cross section assuming a shear modulus of 210 gpa.
