"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. " - Law of the wall fluid dynamics

WebThese laws could be introduced as follows. Consider a system and its surroundings. By definition everything outside of a system is the surrounding. The system is subject to a few laws. Subsections. conservation of mass. Newton's Second Law of Motion. conservation of energy. Second Law of Thermodynamics. WebHowever, your intuition is correct about P2 being at one atmosphere. The driving force for the water coming out of the hole would be due to the height of the column of fluid known as static head. P2 in Sal's original setup would be 1 atmosphere. This means that all of the water would blow out of the canister until the forces balanced at the hole.
