1. A uniform ?ow V ¼ 20i m=s is superimposed on a source of strength 20p m2/s and a sink of equal strength located at (22 m, 0) and (2 m, 0), respectively. The resulting body formed by the appropriate streamline is a Rankine oval. Determine the length and thickness of the oval. Find the velocity at (0, 0).
2. A source near a wall is created by the method of images: superimpose two equal strength sources of strength 4p m2=s at (2 m, 0) and (22 m, 0), respectively. Sketch the ?ow showing the wall and ?nd the velocity distribution along the wall.
Air initially occupying a volume of 1 m3 at 100 kPa, 20°C undergoes two internally reversible processes in series.
Assume that a diaphyseal cross section carries a bending moment M. Let the cross section be circular with inner and outer diameter of 20 and 30 mm, respectively, and assume that the neutral axis (NA) passes through the centroid. Draw the cross sectio..

a frictionless piston-cylinder apparatus contains saturated h2o at 212 degf where 80 of the volume is occupied by vapor
Refrigerant-134a is throttled from saturated liquid state at 7 bar to a pressure of 1.4 bar. Determine the temperature drop during this process and the final specific volume.
A 1.0 litre bottle of water weighs 9.79 N at sea level. If the bottle was taken to the top of Mt Everest (8848 m above sea level), how much would it weight there? Take g at sea level to be 9.81 m/s2 and the radius of the Earth to be 6371 km.
