How are forces exerted in a fluid flow

WebThe pressure exerted by the weight of a fluid is the weight of the fluid (mg) divided by the area A . supporting it, so P=mg/A. The mass of the fluid can be calculated from its volume and density, m = ρV. The volume of the fluid V is related to the dimensions of the water or V = Ah, where A is the cross-sectional area and h is the depth. WebAs the name implies, shear stress refers to the action of a force applied to a material, as indicated by equation 1. 𝞽 = F/A (1) where 𝞽 is the shear stress, F is the applied force, and A is the cross-sectional area parallel to the direction of the applied force. The above equation gives the average shear stress per unit area.
