A cylindrical metal can, 0.1 m high and 0.05 m in diameter, contains liquid helium at its normal boiling point of -452.074 degrees Fahrenheit. At this temperature Helium's heat of vaporization is 20.4 kJ/kg. The walls of the helium container are 1.2 cm thick and have a thermal conductivity of 13.889 W/(m K). The helium container is surrounded by liquid nitrogen at a temperature of -327.64 degrees Fahrenheit.
A. What is the conductive surface area of the metal cylinder?
B. What is the temperature of the liquid helium in Kelvin?
C. What is the temperature of the walls in Kelvin?
D. What is the rate of heat flow into the Helium due to the conduction?
E. How much Helium is lost per hour due to conduction?

A cylindrical can 0.90m high with a diameter of 0.30m is filled
with water to a depth of 0.70m from the bottom. A small hole with a
cross sectional area of 0.004m^2 is in the side of the can at the
bottom. Density of water is 1000kg/m^3 What is the speed of water
flowing out of the bottom of the can?

A closed and elevated vertical cylindrical tank with diameter
2.10 m contains water to a depth of 0.500 m . A worker accidently
pokes a circular hole with diameter 0.0170 m in the bottom of the
tank. As the water drains from the tank, compressed air above the
water in the tank maintains a gauge pressure of 5.00×103
Pa at the surface of the water. Ignore any effects of
viscosity.
A)Just after the hole is made, what is the speed...

Three objects, cylindrical rod (radius = 0.1 m), steel ball
(radius = 0.1 m) and flat screen (length = 0.1 m) with surface
temperature of 65 ℃ are exposed in perpendicular direction to water
flow at 30 m/s and 30 ℃. Assume the area of all three objects are
the same as 1 m2 , determine the individual values of convective
heat transfer coefficient for each object, and their respective
heat loss.

A cylindrical specimen of some metal alloy 8.6 mm in diameter is
stressed in tension. A force of 9070 N produces an elastic
reduction in specimen diameter of 0.0048 mm. Calculate the elastic
modulus (in GPa) of this material if its Poisson's ratio is
0.33.

QUESTION 8
25 mL of 0.1 M acetic acid are titrated with 0.05 M NaOH. At the
equilibrium point of titration, sodium acetate is hydrolyzed by
water:
CH3COO-(aq) + H2O(l) ->
CH3COOH(aq) + OH-(aq)
Calculate the concentration of hydroxide ions, OH-,
and the pH at the equilibrium.
Ka(CH3COOH) = 1.8 x 10-5.
25.00 mL of 0.1 M acetic acid are titrated with 0.05 M NaOH. Calculate the pH...
25.00 mL of 0.1 M acetic acid are titrated with 0.05 M NaOH.
Calculate the pH of the solution after addition of 50 mL of NaOH.
Ka(CH3COOH) = 1.8 x 10-5.
