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 Q/21.
II: The pressure difference between J and N is equal to the pressure difference between J and E.
$$ \text { Which one of the following options is CORRECT? } $$![GATE ME 2024 Fluid Mechanics - Fluid Dynamics Question 2 English](https://app-content.cdn.examgoal.net/fly/@width/image/6y3zli1lx6rv53c/40eacb2f-5afc-4d45-848f-af2b2badb9ec/6ddce080-25f2-11ef-92df-019965141651/file-6y3zli1lx6rv53d.png?format=png)
Steady, compressible flow of air takes place through an adiabatic converging-diverging nozzle, as shown in the figure. For a particular value of pressure difference across the nozzle, a stationary normal shock wave forms in the diverging section of the nozzle. If $E$ and $F$ denote the flow conditions just upstream and downstream of the normal shock, respectively, which of the following statement(s) is/are TRUE?
