m/s, 0.36 m/s and 0.52 m/s respectively.

A capillary-tube viscometer is being selected to measure
viscosity of a liquid food. The maximum viscosity to
be measured will be 230 cP, and the maximum flow
rate that can be measured accurately is 0.015 kg/min.
If the tube length is 10 cm and a maximum pressure
of 25 Pa can be measured, determine the tube
diameter to be used. The density of the product is
1000 kg/m3.

(Laminar flow) Asphalt at 120°F, considered to be a Newtonian
fluid with a viscosity 88,000 times that of water and a specific

pressure gradient is 1.64 psi/ft, determine the flowrate assuming
the pipe is (a) horizontal (ft3/s) (b) vertical with flow up
(ft3/s)

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 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?

1. A fluid exhibiting Bingham plastic flow character is
contained in a tube of diameter d and height The tube is
closed at the bottom to contain the fluid within the tube. If the
bottom is removed, find the conditions under which the fluid will
flow.

A 1.5cm inside diameter tube has water flowing in it at a flow
rate such that the Reynolds number is 50,000. The water enters the
tube at 10oC and the tube wall temperature is maintained
at 15oC higher than the average water bulk temperature.
Calculate:
a) the amount of heat transfer required to achieve a
10oC increase in water temperature (in W)
b) the length of the tube to achieve this amount of heat
transfer (in meters)

Xylene (C8H10, ρ = 704 kg/m3 ) is flowing in a pipe with a
