Question

A horizontal tube has a diameter of 12.0 cm on the left, and then shrinks to 6.5 cm on the right. Clear water enters from the left at 4.0 m / s. We assume that the flow is simple laminar. Calculate:

a- the mass flow of the water entering the tube

b- the velocity of the water to the right

c- if the pressure at the outlet is the atmospheric pressure, what is the pressure at the inlet?

Answer #1

Dear student,

Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.

Thanks for asking ..

In a horizontal pipe, water enters with a velocity of 2m / s
when it is subjected to a pressure at the inlet of 200 Pw (water
pressure). Determine:
a) The speed of the water (in m / s) at the outlet if an outlet
pressure of 134 Pw is observed
b) If the area of the tube at the inlet is 0.75m2,
find the volumetric flow at the outlet.
(in m3 / sec)

A smooth tube 5 cm in diameter and 450 cm in length is
placed inside another tube larger in diameter. Air enters the
smaller diameter tube at a pressure of 5 bars, a mean temperature
of 16 oC , and at a flow rate of 29 gm/s. saturated
steam at 1.523 bar in the annulus between the two tubes condenses
on the surface 0f the inside tube find:
The outlet temperature of air
The outlet pressure of air
The mass...

Steam enters a long, horizontal pipe with an inlet diameter of d1 =
16 cm at 2 MPa and 300 degrees Celsius with a velocity of 2.5 m/s.
Farther downstream, the conditions are 1.8 MPa and 250 degrees
Celsius, and the diameter is d2 = 14 cm. Determine (a) the mass
flow rate of the steam and (b) the rate of heat transfer.

Pressurized Water is heated in a thin tube with a diameter of 60
mm. water enters with a mass flow rate of 0.01 kg/s and an inlet
temperature of 20°C. a uniform heat flux of 2000 W/m2 is applied to
the tube. What is the required length of the tube to obtain an exit
temperature of 80°C for the water? If the water reaches 80°C at the
outlet, what is the surface temperature of the tube at the
outlet?

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.

The water enters the two-story building through a horizontal
pipe with an inner diameter 4 cm and the
pressure of 10 atm. The velocity of the water flow in the pipe
is 5 m/s. The horizontal pipe is connected
to a vertical pipe which leads to bathrooms in each story.
a) What is the velocity of the water flow in the vertical
pipe
if the diameter of the pipe is 2 cm.
b) What is the pressure in the pipe...

In a section of horizontal pipe with a diameter of 4.0 cm, the
pressure is 115 kPa and water is flowing with a speed of 1.5 m/s.
The pipe narrows to a 3.0-cm diameter. What is the pressure in kPa
in the narrower region? Treat the water as an ideal incompressible
fluid.

The tube shown has a length of 2.00 m and a diameter of 1.00 mm.
Water at 40° C is flowing through the tube.
For water at 40° C:
A) What pressure difference is required to give the water a flow
speed of 4.0 m/s? (Give your answer in units of Pa.)
B) What force applied to the end of the tube will produce this
pressure? (Give your answer in units of N.)
C) What is the volume flow rate...

Combustion gases passing through a 2.3-cm-internal diameter
circular tube are used to vaporize waste water at atmospheric
pressure. Hot gases enter the tube at 115 kPa and 250°C at a mean
velocity of 5 m/s, and leave at 150°C. If the average heat transfer
coefficient is 120 W/m2 °C and the inner surface temperature of the
tube is 112°C, determine the tube length. Answer in cm with two(2)
decimal places.

The
hose has a diameter of 2.5 cm, but the nozzle has a diameter of
only 1.10 cm. The water that comes out of the hose fills a
container of 25 Len 1.50 min. Calculate: a- the volume flow flowing
through the hose b- the velocity of the water leaving the nozzle c-
if the pressure external to the hose is atmospheric, what is the
absolute pressure of the water inside the hose?
