In the pipe network shown in the figure, all pipes have the same cross-section and can be assumed to have the same friction factor. The pipes connecting points W, N, and S with point J have an equal length L. The pipe connecting points J and E has a length 10L. The pressures at the ends N, E, and S are equal. The flow rate in the pipe connecting W and J is Q. Assume that the fluid flow is steady, incompressible, and the pressure losses at the pipe entrance and junction are negligible. Consider the following statements: I: The flow rate in pipe connecting J and E is $\frac{Q}{21}$ . II: The pressure difference between J and N is equal to the pressure difference between J and E. Which one of the following options is CORRECT?
