A sub-marine which may be supposed to approximate a cylinder 4m in diameter and 20m long travels sub- merged at 1.3m/s in seawater. Find the drag exerted on it, if the drag co-efficient for Reynold number greater than 105 may be taken as 0.75. The density of seawater is given as 1035kg/m³ and kinematic viscosity as 0.015 stokes.
