Question

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).

Answer #1

A pipe has a cross sectional area of 10 cm2 with an
unknown fluid, density of 1150 kg/m3 moving at a speed
of 3 m/s and has a pressure of 1.4 atm. The pipe then lowers down
2.5 meters and narrows to a cross sectional area of 2.5
cm2. What is the speed of the fluid? 1 atm = 1.01 x
105 Pa.

A water pipe tapers down from an initial radius of R1
= 0.2 m to a final radius of R2 = 0.09 m. The water
flows at a velocity v1 = 0.86 m/s in the larger section
of pipe.
1. Using this water supply, how long would it take to fill up a
swimming pool with a volume of V = 130 m3? (give your
answer in minutes)
2. The water pressure in the center of the larger section of...

1. A hydraulic lift uses a compressor to compress the hydraulic
fluid with a moving piston (piston A) of radius RA = 4.83 cm. A
second piston (piston B) of radius RB = 18.48 cm is used at the
lift to lift cars. What force must be applied by piston A to lift a
14,871N car with piston B?
2. When a 0.438 kg mass is hung from a certain spring it
stretches 0.119 m to its equilibrium position at...

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 (va = 0.3 ·
10-6m2/s, cpa =...
