Answer #1

g = 9.81 m/s².
The standard properties of water are density:
ϱH2O=1kg/dm3ϱH2O=1kg/dm3 exactly, kinematic viscosity:
νH2O=1.02⋅10−6m2/s
The specification of a certain liquid states that its specific
gravity is 0.661, its viscosity is 84.1 cPo (centipoise). Express
the physical properties of this material in one of the given SI
units.
Density (in kg/m3):
Specific weight (in N/m³):
Dynamic viscosity (in mPa·s):
Kinematic viscosity (in m²/s):

In order to describe fluid film flow over walls, few variables
are considered including fluid density,
acceleration due to gravity, length, and dynamic viscosity.
Use Rayleigh’s method to find the
dimensionless number that may be used for describing fluid
films over the walls.

Determine the specific mass or density, specific weight,
specific volume and specific gravity of a fluid having a volume of
10 litres and a weight of 0.005 GN.

A 2 m long pipe with a diameter of 30 cm carries a fluid of
density 1051 kg/m3 and kinematic viscosity of 1.72 X 10^-5 m2/s .
If the fluid in the center of the pipe is traveling at 5.5 m/s,
what is the force needed to keep the pipe in place. Use the
Blassius solution where needed.

Fluid with a specific gravity of 1.3 is flowing through a pipe
of 1.1 m diameter. Considering dynamic viscosity of 0.3
N.s/m2 determine the type of flow for a velocity of 1.6
m/s, 0.36 m/s and 0.52 m/s respectively.

Fluid is flowing through the pipe with radius of 2 m at the
rate of 8 m/s. if fluid’s kinematic viscosity is 1.004 x
10-6 m/s2, and pipe’s roughness is 0.015 x
10-3 m.
Set up Colebrook equation for friction factor.
Solve the equation either by using solver or by plugging in a
value from Moody’s chart and iterating, if necessary.
Determine pressure drop, if fluid’s dynamic viscosity is 1.0035
x 10-3

The properties of the fluid are: density 895 kg/m3,
viscosity 0.76 mNm-2s. A double-pipe heat exchanger is
to be used to heat 6000 kg/h of 22 mol per cent hydrochloric acid.
The exchanger will be constructed from karbate (impervious carbon)
and steel tubing.
The acid will flow through the inner, karbate, tube and
saturated steam at 100ºC will be used for heating. The tube
dimensions will be: karbate tube inside diameter 50 mm, outside
diameter 60 mm; steel tube inside...

An
object floats first in fluid of density p(1)=900 kg/m^3, then in a
fluid of density p(2)=1000 kg/m^3, and finally in a fluid of
density p(3)=1100 kg/m^3.
a) Rank the densities according to the magnitude of the
buoyant force on the object, greatest first.
b) Rank the densities according to the amount of fluid
displaced by the object, greatest first.

(a) Fluid at a mass flow rate of 0.352 kg/s flows through a tube
with a diameter of 15 mm and a length of 25 m. The inner surface of
the tube is heated with a uniform heat flux of 1000 W/m2.
Measurements shown that the inlet temperature of the fluid is 30
˚C. Assume the outer surface of the tube is perfectly insulated.
Consider the thermophysical properties of the fluid are as follows:

A liquid of density 1343 kg / m 3 flows with speed 2 . 21 m / s
into a pipe of diameter 0 . 21 m . The diameter of the pipe
decreases to 0 . 05 m at its exit end. The exit end of the pipe is
4 . 41 m lower than the entrance of the pipe, and the pressure at
the exit of the pipe is 1 . 2 atm Applying Bernoulli’s principle,
what is...
