Document Summary
A liquid or gase that cannot support shear forces. Important law given by pascal: the pressure at any given point in a fluid is the same in all directions. This is one of the key things to remember. If you have a point in a fluid, the pressure is acting in all direction. Pressure is equal to force divided by area, same as stress: maximum pressure acts perpendicular to any surface, pressure increases linearly with depth in the fluid. P = density = mass / volume. Weight = p * q * volume. Sum of fy = 0 (p + dp)da pda - (density*q * da *dh) = 0. Therefore, change in p = density*q* delta h and . P = p0 * density*q * h. Determine the minimum wall thickness to prevent it from overturning. Pressure is acting on the surface cd in triangle diagram.
