Question

A steel pipe system with a nominal diameter of 1 NPS sch. 40, transports 2.0 L / s of water at 25 ° C. The flow is divided into two flows, by two pipes of 1⁄2 NPS and 3⁄4 NPS sch. 40. The Speed along the 1⁄2 NPS line is 9.84 ft / s. Determine the volumetric flows 1,2,3 and the speeds along lines 1 and 3.

Answer #1

The water flowing through a 2.0 cm (inside diameter) pipe flows out
through three 1.4 cm pipes. (a) If the flow rates
in the three smaller pipes are 24, 15, and 11 L/min, what is the
flow rate in the 2.0 cm pipe? (b) What is the
ratio of the speed of water in the 2.0 cm pipe to that in the pipe
carrying 24 L/min?

Xylene (C8H10, ρ = 704 kg/m3 ) is flowing in a pipe with a
diameter of 100 mm at a velocity of 2.2 m/s. (a) Calculate the
volumetric flow rate in m3 /s. (b) Calculate the mass flow rate in
kg/s. (c) Calculate the molar flow rate in mol/s. (d) The 100 mm
pipe is joined to two smaller pipes with diameters of 25 mm and 50
mm respectively. If the velocity of the n-Octane in the smaller
pipe is...

By what factor does the speed of the water increase moving from
the larger to smaller pipe?

A concentric tube heat exchanger is comprised of a stainless
steel (ks = 40 W/mK) inner pipe, NPS 2- nominal schedule
40 size (corresponding to an inner diameter of 52.5 mm and an outer
diameter of 60.3 mm), and an outer stainless steel pipe of NPS
3-nominal schedule 40 (ID = 77.9 mm, OD = 88.9 mm). The heat
exchanger has an effective length of 35 m.
The inner pipe fluid is ammonia (?a = 0.3 · 10?6

1. Fluid flows at a rate of 2.0 L/s through a pipe with a
diameter of 10 cm. The pipe then goes up a height of 5m while
narrowing to a diameter of 5 cm. What is the pressure gradient (the
change in pressure) from the top to the bottom of the pipe? [hint:
draw this and label with P1, v1, P2, v2 etc.)
2. A hurricane wind blows across the top of a flat roof
measuring 12 m by...

A 250 mm diameter of cast iron pipe flows 39.3 L/s of
SAE 10 oil along 500 m length. Given: dynamic viscosity, μ and
density, ρ of SAE 10 oil are 1.04 x 10-1 Ns/m2 and 917 kg/m3
respectively. By assuming the flow is laminar, determine energy
head and pressure loss due to pipe friction using Hagen-Poiseuille
equation and friction factor, f.

1.) A liquid of density 1390 km/m^3 flows steadily through a
pipe of varying diameter and height. At Location 1 along the pipe,
the flow speed is 9.31 m/s and the pipe d1 diameter is 10.3cm . At
Location 2, the pipe diameter d2 is 17.5 cm . At Location 1, the
pipe is triangle y= 9.31m higher than it is at Location 2. Ignoring
viscosity, calculate the difference between the fluid pressure at
Location 2 and the fluid pressure...
