in a flow system with two pipes in parallel, the flow rate in each pipe will be such that

a) the flow rate in each pipe is the same

b) the velocity in each pipe is the same

c) the Reynolds Number in each pipe is 10^5

d) the head loss in each pipe is the same

e) the diameter doesn\'t affect the flow

Solution

d) The flow rate of the pipes will vary, and the head loss in the system remains the same.

Assuming the diameter of the pipes to be same, the Dynamic pressure of the system 1/2 x rho x v^2 remains averaged along the entire pipes in parallel to maintain a constant mass flow rate according to the law of conservation of the mass. Rho x A x V = constant.
