F-dr = 47 for a vector function F = (2x -y)i A line integral is evaluated as yzz -y?zk acting on the curved surface S, where S is the upper half of the sphere x2+y2+ 22 = 22 and c is its boundary with counter-clockwise direction viewed from the top, as shown in Figure 3.2 below. Use Stokes' theorem by evaluating the double integral to verify the given value of line integral. Satu kamiran garis dinilai sebagaiF.dr = 4r untuk...
(4 Marks/Markah) b) A supersonic wind tunnel nozzle is to be designed for Mach number, Ma = 2.5 with a test section I m' in area as shown in Figure 2. The supply pressure and the temperature at the nozzle inlet, where the velocity is negeligible, are 8 x 10° Pa and 27Crespectively. The preliminary design is to be based on the assumptions that the flow is isentropic, with k =1.4, R = 287 Jkg.K, and that the flow is...
