1) The fundamental variables considered in kinematic problems are only length and time. 2) In the SI unit system, force is taken as the fundamental variable. 3) Imagine two fluids, one with high viscosity and the other one is not. When we pour these fluids into two different identical glasses, water in the glass fluctuates more in the case of fluid with high viscosity. 4) In kinematics, for fluid mechanics, the presence of the term "convective acceleration" make it more difficult compared to solid mechanics. 5) In non-Newtonian fluids, the solution of the same hydrostatic problems is more complicated compared to that of Newtonian fluid. 6) Shear stresses in a hydrostatic domain are always equal to zero. 7) In a hydrostatic domain, imagine two different fluids, one with higher viscosity and thẹ other one is with lower viscosity. The specific weight of these fluids is the same. When these two fluids (with the same volumé) placed into the identical tanks in terms'of size, the fluid with higher viscosity create higher pressure at the bottom of the tank. 8) The difference between absolute pressure and relative pressure is equal to atmospheric pressure. 9) According to Pascal's law, the pressure is the same in all points of water-filled vessels. 10) There is a linear relationship between pressure and depth in a hydrostatic environment for Bingham fluid (non-Newtonian Fluid).

Transcribed Image Text:1) The fundamental variables considered in kinematic problems are only length and time.
2) In the SI unit system, force is taken as the fundamental variable.
3) Imaginę two fluids, one with high viscosity and the other one is not. When we pour these fluids into two different identical glasses,
water in the glass fluctuates more in the case of fluid with high viscosity.
4) In kinematics, for fluid mechanics, the presence of the term "convective acceleration" make it more difficult compared to solid
mechanics.
5) In non-Newtonian fluids, the solution of the same hydrostatic problems is more complicated compared to that of Newtonian fluid.
6) Shear stresses in a hydrostatic domain are always equal to zero.
7) In a hydrostatic domain, imagine two different fluids, one with higher viscosity and thẹ other one is with lower viscosity. The specific
weight of these fluids is the same. When these two fluids (with the same volumé) placed into the identical tanks in terms'of size, the
fluid with higher viscosity create higher pressure at the bottom of the tank.
8) The difference between absolute pressure and relative pressure is equal to atmospheric pressure.
9) According to Pascal's law, the pressure is the same in all points of water-filled vessels.
10) There is a linear relationship between pressure and depth in a hydrostatic environment for Bingham fluid (non-Newtonian Fluid).
