A cylindrical storage tank contains liquefied propane under a pressure of 1.5 MPa (gage pressure P=1.5 MPa) and is subjected to a torque T=5 kN-m. Knowing that the tank has an inner diameter of 320 mm and a wall thickness of 3 mm, find the principal stresses and determine the maximum shear stress.

A cylindrical air tank has dimensions diameter = 0.2m and height
0.8m. an attached pressure gage reads 200 kPa and the temperature
is 27 celcius. an electrical heater is energized inside and it
raises the temperature to 147 celius in 2 minutes. Calculate the
mass of air in the tank (kg) (have to use ideal gas law, molecular
weight of air)

You need to design a relief valve for a new pressurized propane
storage tank. As part of the design process, you need to calculate
the maximum pressure inside the tank for any feasible “worst case”
scenario. One of your design cases is that a fire breaks out
beneath the tank, causing the liquid propane inside to rapidly heat
up to 250°F. The tank is a rigid 10 ft3 vessel that holds 150 lbm
of propane. What is the pressure inside...

A tank that initially contains H2O at 0.05 MPa and 100 ºC, is
connected to a water vapor line at 0.60 MPa and 200 ºC and is
filled to a level where 90% (on a volumetric basis) is liquid. The
1 m3 tank is kept at 100 ºC during the process. Determine the
quality of the gas in the second phase, the input mass in (kg) and
the heat transfer, in kJ.

Steam is contained in a 4-liter volume at a pressure of 1.5 MPa
and a temperature of 200°C. If the pressure is held constant by
expanding the volume while 40 kJ of heat is added, find the final
temperature. use enthalpy.

The propane is contained in a piston-cylinder assembly, which
maintains constant pressure at 0.2 MPa. If a mixture with a quality
of 0.65 and a total volume of 0.07 m3 is slowly heated to a
temperature of 54°C, a) what was the total work into the system b)
what was the total amount of heat added to the system.
Please explain what tables you use to find the answer.

A spherical storage tank contains oil. The tank has a diameter
of 6 feet. You are asked to calculate the height at which an
8-foot-long dipstick would be wet with oil when immersed in the
tank when it contains 6 ft3 of oil. The equation giving
the height h of the liquid in the spherical tank for the given
volume and radius is given by:
f(h) = h3−9h2 + 3.8197
Use the secant method to find roots of equations to...

A steel tank contains water at ? = 1.00 MPa and ℎ = 3100 kJ/kg.
Determine the following:
a. State of the water; ie whether the water is compressed water
or saturated water or superheated vapour? (Hint: Use Saturated
water—Pressure table to compare ℎ at ? = 1.00 MPa)
b. Estimate the temperature of the water. (Hint: Use Saturated
water—Pressure table or Superheated water, depending on the state
you find in a)
c. Other properties of water in the tank...

A closed and elevated vertical cylindrical tank
with diameter 2.00m
contains water to a depth of
0.900m
. A worker accidently pokes a circular hole with
diameter 0.0190m
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 of5.00�103Pa
at the surface of the water. Ignore any effects of
viscosity.
A. Just after the hole
is made, what is the speed of the water as...
