Hi please could you jelp with this question and explain the method next to calcs?In the picture there are three bridge piers of diameter d=0.3m.The bridge must withstand a max flow rate of 70m3/s. Ignore surface effects and only consider the shaded region. The kinematic viscosity of water v=10^(-6). Determine the total drag force.
