1.A smooth prolate spheroid has its major axis make an angle alpha with the free stream. The major axis has a length 2a and the minor axis has length 2b. The flow is incompressible, but friction and inertia influences the flow pattern. Use dimensional analysis.
Find the dimension parameters that affect the drag coefficient.
2.It is desired to transmit 300mm^3/s of gasoline at 20 degree Celsius through a 650mm long horizontal tube with a head loss of 500mm Find the diameter of the tube to accomplish this.
