An incompressible liquid flows (in steady state) through a horizontal tubular pipe with a cross section area of S1. The pipe with area S1 goes over in a second, also tubular shaped pipe, with a cross sectional area of S2 (see figure). Given: v1=10m/s;A1=102m2,A0=2.102m2, density water =1000kg/m3. Calculate the external force that has to act on the flange so that the diffuser keeps in its original position
