Answer:
To run. The machine one at a time
Explanation:
Answer:
Equation of the streamline V = 4i - 4j m/s
Unit Vector n = (4i+4j)/4√2
Explanation:
Parameters
x=2 and y=-1
V=(2x)i + (yt)j m/s
Substituting (x=2) and (y=-1) into the velocity field V
Therefore V = 4i - tj where t=4s
Equation of the streamline
V = 4i - 4j m/s
Unit vector normal to the streamline n
Note V.n=0 and the velocity only have x- and y - components
Therefore
V.n=(4i - 4j).(nₓi+nyj)=0 or 4nₓ - 4ny = 0
The unit vector requires that nₓ^2+ny^2=1
Therefore n = (4i+4j)/4√2
