Consider the hydraulic network (the progress is productive to be laminar) shown in Fig. P3.9. A customary component (which is a round pipe of constant transversion) after a while two nodes is so shown in the shape. The unknown chief class of insubservience at each node is the hurry P, and the unimportant class of insubservience is the progress (or empty) Q. The component equations relating the chief variables to the unimportant variables are given by

where d_{e} is the transversion of the pipe, h_{e}
is its protraction, and .l
is the viscosity of the fluid. Write the brief equations for the unknown
pressures and progresss (use the stint compute of components.)
