2) 1) The velocity field for a particular plane flow (w=0) of air is given by U(x,y)=4y^2/x^2+y^2 V(x,y)=-4x/x^2+y^ 2 show that this is an imcompressible.
2) Find the unit vector normal to the stream line at the point (-2,-1) when t= 2s if the velocity field ia given by :
a) V=2xyi+y^2tj m/s
b) V= 2y(x-y)i +xytj m/s
3) A step-up transformer has 21 turns on the primary coil and 800 turns on the secondary coil. If this transformer is to produce an output of 4500 V
V with a 11-mA
mA current, what input current and voltage are needed?
