Explanation:
please follow me and make me as brainlist.
Answer:
The resultant velocity is 7.81m/s and
The direction of resultant velocity is 39.79°
Explanation:
The proper question is
"A stream function is given by: Y= 5x-6y.
A stream function is given by: Y= 5x-6y.Calculate the velocity components and also magnitude and direction of the resultant velocity at any point."
Given that,The stream function is
We know that the components of stream.function and velocity are related as follows
Hence,substituting the given stream function the above two relations,we get
The components of velocity are known.We know that velocity is written as
Magnitude of velocity is given as
Direction of velocity at any point is given by relation
Substituting the known values we get
