Externet Posted August 31, 2005 Share Posted August 31, 2005 Hi. What is the force exerted on a 1m² vertical plate held transversal submerged in a river flowing laminar at 0.5m/s ? Link to comment Share on other sites More sharing options...
CPL.Luke Posted August 31, 2005 Share Posted August 31, 2005 is this for homework? Link to comment Share on other sites More sharing options...

Force equals Cd times Area times density/2 times velocity squared. Water is 1000 kg per cubic meter so you know everything except the Cd, the coefficient of drag. IIRC it should be about 1.2 if the plate is square and placed deep enough so that there is no significant surface effect. If the plate is rectangular it should be somewhat higher but less than 2.0 Link to comment Share on other sites More sharing options...
