At 130°C, a bronze hoop 20 mm thick whose inside diameter is
600 mm just fits snugly over a steel hoop 15 mm thick. Both hoops
are 100 mm wide. Compute the contact pressure between the hoops
when the temperature drops to 20°C. Neglect the possibility that
the inner ring may buckle. For steel, E = 200 GPa and α =
11.7μm/(m.°C). For bronze, E = 83 GPa α = 19 μm/(m.°C)

A cast iron water pipe of 500 mm inside diameter and 20 mm
thick, is supported over a span of 10 meters. Find the maximum
bending stress in the pipe metal, when the pipe is running full.
Take density of cast iron = 70.6 kN/m3 and water = 9.8 kN/m3

A centrifugal pump has an eye diameter and an impeller diameter
of 300 mm and 600 mm respectively while running at 850 rpm. When
rotating, the blade angle is measured at 35o at the
outlet with considering the tangent. The flow velocity is limited
at 5 m/s constantly. Determine the following;
(a) inlet blade angle
(b) outlet absolute velocity with its angle at outlet and
(c) the manometric head.

A neon sign is made of glass tubing whose inside diameter is 2.5
cm and whose length is 5.5 m. If the sign contains neon at a
pressure of 1.73 torr at 37 ∘C, how many grams of neon are in the
sign? (The volume of a cylinder is πr2h.) Express your answer using
two significant figures.

130 kg of uniform spherical particles with a diameter of 60 mm
and particle density 1500 kg/m3 are fludised by water
(density 1000 kg/m3, viscosity 0.001 Pa s) in a circular
bed of cross-sectional area 0.2 m2. The single particle
terminal velocity of the particles is 0.98 mm/s and the voidage at
incipient fludisation is known to be 0.47. Determine:
a. The minimum fludised velocity
b. height when the liquid flow rate is 2x10-5
m3/s.

A 12-in-diameter well completely penetrates a 130-ft-thick,
unconfined aquifer with a coefficient of permeability of 0.00055
ft/sec. If the radius of influence of the well is 500 feet and the
drawdown at an observation well 250 ft away is 5 ft, determine the
steady state well discharge and the drawdown at the well.

The propeller shaft of a large ship has an outside diameter of
350 mm and inside diameter 250mm. the shaft is rated for a maximum
of shear stress 62 MPa.
1) if the shaft is runnning at 500 rpm what is the maximum power
that can be transmitted without exceeding allowable stress.
2) if the rotational speed of the shaft is doubled but the power
requirements unchanged what happens to the shear stress in the
shaft? calculate valures.
