Problem $1$: True or False $[25$ points $-5$ points each$]$

a$)$ In fluid systems, shear stress is maximum at the walls. True or False. Provide a brief explanation.

b$)$ In fluid flows, viscous forces depend on how rapidly velocity changes within the space. True or False. Provide a brief explanation.

c$)$ In analyzing fluid statics, viscous forces significantly contribute to the system's momentum balance. True or False. Provide a brief explanation.

d$)$ Air is a compressible fluid; however, one can reasonably assume a flow of air is incompressible if the velocity is less than $30\%$ of the speed of sound in the studied air. True or False. Provide a brief explanation.

e$)$ Viscosity of liquids increases with temperature. True or False. Provide a brief explanation.

f$)$ Water in the container shown in the figure below is at rest. Pressure at point A is larger than at point B$.$ True or False. Provide a brief explanation.
