An 18-in diameter pipeline (L = 30,000 ft, ε = 0.0045 ft) connects
2 water reservoirs. The upstream reservoir elevation is 825 ft and
the downstream reservoir elevation is 600 ft.
a) Assume f = 0.023 and calculate steady state flow rate (ft3/sec)
in the pipeline
b) Check validity of friction factor assumption if water
temperature is 50°F
c) Briefly explain why your calculated velocity in this pipe is
acceptable

Inside the wall of a house, an L-shaped section of hot-water pipe
consists of three parts: a straight, horizontal piece h =
28.0 cm long, an elbow, and a straight vertical piece ℓ = 156 cm
long (figure below). A stud and a second-story floorboard hold the
ends of this section of copper pipe stationary. Find the
magnitude and direction of the displacement of the
pipe elbow when the water flow is turned on, raising the
temperature of the pipe...

City water will be cooled in a heat exchanger by sea water
entering at 15°C. The outlet temperature of the sea water is 20°C.
City water will be recirculated to reduce water consumption. The
suction line of the pump has an inner diameter of 154 mm, is 22 m
long, and has two 90° bends and a hinged check valve. The pipe from
the pump to the heat exchanger has an inner diameter of 127 mm, is
140 m long,...

Water at 15°C enters a tube of 2 cm of diameter with flow rate
3953 kg/h. Assume the ratio L/D>10, and the wall temperature is
constant at 80-C. The outlet temperature is 50°C The properties of
water at the film temperature are density rho = p = 985 kg/m3,
specific heat Cp = 4180 J/kgk, conductivity k = 0.651 W/mK, dynamic
viscosity mu= u = 4.71 × 10- kg/ms, At the wall temperature of 80°C
we have dynamic viscosity muw=...
