At constant flow rate, closing pipe number 4 increases the flow through the other 3 by the factor $$ C_1 + C_2 + C_3 + C_4 \over C_1 + C_2 + C_3 $$ For non-rigid pipes, you just need to know the R as a function of the pressure. This article briefly explains what happens to fluids flowing through pipes. Based on the work of Dean (1927 and 1928) [1-2] and Cuming (1952) [3], the stationary flow of an incompressible Newtonian fluid through a curved pipe of uniform curvature and with elliptic cross. If you attempt to push that same flow through a small pipe the discharge pressure will increase and the flow will decrease.
