In the case of turbulent flow of a fluid through a circular tube (as compared to the case of laminar flow at the same flow rate) the maximum velocity is ...................., shear stress at the wall is ................................., and the pressure drop across a given length is ____________. The correct words for the bllanks are, respectively:

Consider the saline drip bottle shown. If $$\rho $$ is the density of saline, find
(a) Pressure at $$A,$$
(b) The velocity of flow of saline through the tube. (Neglect viscous losses in tube). Atmospheric pressure $${P_{atm}}.$$

When a Pitot-static tube is immersed in a water stream (density $${\rho _w}$$), the differential head measured by a mercury (density $${\rho _m}$$ manometer is $${h_m}.$$ What is the velocity of the water stream?

A mercury manometer is attached to a section of the pipe shown in the figure. Mercury levels are indicated when there is no water flowing through the pipe. When water starts flowing through the pipe continuously at constant rate in the direction of the arrow, the level of mercury at $$B:$$
