Textbook Question
Chapter 8, Problem 114P
Investigate the effect of tube length on water flow rate by computing the flow generated by a pressure difference Δp= 100 kPa applied to a length L of smooth tubing, of diameter D = 25 mm. Plot the flow rate against tube length for flow ranging from low speed laminar to fully turbulent.

A pipe is often used to assess the
flow rate of water in the center of a
pipe with an internal diameter of
102.3 mm at 20°C (density =
998.3 kg/m3, viscosity = 1.005
CP). The pitot tube coefficient is
0.98, and the manometer reading
is 10 mm of mercury at 20°C
(density = 13,545. 85 kg/m3).
Compute the velocity at the
center and the water's volumetric
flow rate
Compute the head loss (in meters) in 2000 m of horizontal, steel pipe with nominal pipe size of
300 mm and SCH 30. The pipe is carrying water with an average velocity of 1.88 m/s. Take water
at 20°C to have a viscosity of 1.00E-3 Pa-s and density of 1000 kg/(m^3). Take the roughness of
steel pipe to be 0.048 mm.
Round your answer to 2 decimal places.
