Question: q1 an incompressible flow field is given by va axbyi...

Question details

Q1/ An incompressible flow field is given by: Va (Ax+By)i- Ay j Where A-1 sec, B 2 sec and the coordinate are measured in meters Find the magnitude and direction of the acceleration of a fluid particle at point(x,y) (1,2).
02/ Calculate the torque necessary to rotate an inner cylinder at 2-10 rad/sec if the outer one is fixed. The two radii are 25mm and 26mm. Water fills the gap between the 100 mm long cylinders, and 6.6x10 mTsec
