Hydraulics and Fluid Mechanics in ME Whenever a plate is held immersed at some angle with the direction of flow of the liquid, it is subjected to some pressure. The component of this pressure, in the direction of flow of the liquid, is known as Lift Bulk modulus Stagnation pressure Drag Lift Bulk modulus Stagnation pressure Drag ANSWER DOWNLOAD EXAMIANS APP
