Homework Answers
Sorry the question is not clearly visible.. your finger has hidden the discharge at node C
You can attempt to solve it as follows
Equate the energies at nodes to the energy of point of inlet.. i.e. equate kinetic and potential energy of point A with respect to other points.. and there you go
You will find pressure heads
Add Answer to:
C= 20 L/S
