Question

**A** fluid with SG:0,888 and viscosity:0,8 Pa s
flows in horizontal pipe of diameter:5 cm and length:40 m.The
measured velocity profile is of parabolic shape.The amount of
pressure difference between inlet and exist of the pipe is 648,76
kPa.Determine Reynolds number of flow if the pipe is inclined at an
angle 30 degree with horizontal and flow is upward with the same
pressure difference is
applied

Answer #1

The above calculations shows the generalised procedure to calculate the Reynolds number.

Re = 8766

given that the velocity profile is parabolic and parabolic profile will only obtain in Laminar flow

and for Laminar flow through pipe the Reynolds number should be below 2000, hence there might be some mistake with given data, please verify the given data and perform the above mentioned steps.

A fluid is flowing under laminar conditions in a cylindrical
pipe of 2 cm diameter. The pressure drop is 330 Pa, the viscosity
of the fluid is 5 Pa.s, and the pipe is 300 cm long. Calculate the
mean velocity and velocity of fluid at different radial locations
in the pipe

Consider a horizontal pipe in which a viscous fluid is moving at
a laminar flow. The pressure drop across a 0.2-cm ID pipe was
measured at 18,000 Pa/m. The fluid has a rho= 1110 kg/m3 and mu=
0.03 kg/m-s. Determine the equation that defines the velocity
profile vz(r).Then, calculate the velocity at the center of the
pipe (vzat r = 0 in m/s).

A horizontal pipe 20.00 cm in diameter has a smooth reduction to
a pipe 10.00 cm in diameter. If the pressure of the water in the
larger pipe is 7.50 104 Pa and the pressure in the smaller pipe is
6.00 104 Pa, at what rate does water flow through the pipes?

A fluid of viscosity 0,002 N-s /m2 and density 1000 kg/m3 flows
with an average speed of 1 m/s in a 2 cm-diameter horizontal smooth
pipe . Calculate
a)magnitude of shearing stress at the pipe wall.
b) shear stress velocity of flow
c) magnitude of pressure gradient to induce flow

A liquid of density 1270 kg/m3 flows steadily through
a pipe of varying diameter and height. At Location 1 along the
pipe, the flow speed is 9.81 m/s and the pipe diameter d1 is 11.3
cm. At Location 2, the pipe diameter d2 is 17.1 cm. At Location 1,
the pipe is Δy=9.59 m higher than it is at Location 2. Ignoring
viscosity, calculate the difference ΔP in units of Pa between the
fluid pressure at Location 2 and the...

A horizontal pipe (Venturi Tube) 10.0 cm in diameter has a
smooth reduction to a pipe 5.00 cm in diameter. If the pressure of
the water in the larger pipe is 3.5 x 105 Pa and the
pressure in the smaller pipe is 6.0 x 104 Pa, at what
rate does water flow through the pipes. Hint: Use the continuity
equation to express one speed in terms of the another.

Water flows through a constricting pipe. At the inlet, the
pressure is 100,000 Pa, the diameter is 1.6 m and the water flows
at 1 m/s. The centerline of the outlet of the pipe is the same as
the centerline of the inlet of the pipe. Solve for the PRESSURE and
VELOCITY of the water exiting the pipe if the diameter is 0.8
m.
I know Bernoulli's equation, it's the solving for two unknowns
that has me lost.

Water flows at a rate of 30 L/min through a horizontal
7.0-cm-diameter pipe under a pressure of 80 Pa. At one point,
calcium deposits reduce the cross-sectional area of the pipe to 20
cm^2. What is the pressure at this point? Consider the water to be
an ideal fluid.

Water, with a density of ?=1185 kg/m3 , flows in a horizontal
pipe. In one segment of the pipe, the flow speed is ?1=7.13 m/s .
In a second segment, the flow speed is ?2=1.57 m/s . What is the
difference between the pressure in the second segment ( ?2 ) and
the pressure in the first segment ( ?1 )?

Given: The viscosity is negligible. Atmospheric pressure is
101300 Pa. Water flows at speed of 5.9 m/s through a horizontal
pipe of diameter 3.3 cm. The gauge pressure P1 of the water in the
pipe is 1.6 atm. A short segment of the pipe is constricted to a
smaller diameter of 2.4 cm.
What is the gauge pressure of the water flowing through the
constricted segment? Answer in units of atm.
