a$)$ List any two "critical depth meters" that you know

b$)$ State Newton's law of viscosity and explain all tems

c$)$ Explaining all terms, write the equation for the energy loss in a hydraulic jump:

d$)$ Give $4$ types of "local" head losses that can occur in a pipeline

e$)$ A pipeline $400mm$ in diameter and $2000m$ long comects two reservoirs whose difference in head is $6m.$ Ignoring local head losses, determine the discharge in the pipe if the friction factor is $0\mathrm{.}006$
