A hot liquid is filled in a spherical tank with an inner
diameter of 3 m and a wall thickness of 3 cm. The tank wall is made
of a material with a thermal conductivity of 0.15 W/m∙K. The hot
liquid in the tank causes the inner surface temperature to be
100°C, while the tank outer surface is exposed to air at 20°C and
has an emissivity of 0.35. Determine the outer surface temperature
of the tank. Assume that the properties of air can be evaluated at
40°C and 1 atm pressure. Is this a good assumption?

A cylindrical tank with inner diameter 2.0 m is designed to
operate as a fluidized bed reactor for a heterogeneous catalytic
reaction. The tank is loaded with a random packing of cubic
particles to a height of 4.0 m with voidage 0.4 before the
fluidization process. The density and length of each side of the
cubic particles are 2600 kg m-3 and 1.0 cm respectively. During
operation, a liquid reactant with density 1000 kg m-3 and viscosity

The 1.3-m-diameter tank is initially filled with gasoline. There
is a 3.2-cm-diameter orifice in the bottom. If the orifice is
suddenly opened, estimate the time (minutes) for the fluid level to
drop from 2m to 1.2 m. Use SG (gas) = 0.66, Cd = 0.63

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

A large tank containing a mystery liquid is filled to a depth of
L = 35 m. The upper surface of the liquid is
exposed to the atmosphere (of density 1.2
kg/m3). A pipe of cross-sectional area
Ain = 0.01 m2 is inserted in
to the liquid. The other ’outlet’ end of the pipe, of smaller cross
sectional area Aout = 0.005
m2, is placed outside the
liquid at a height of h = 2 m below the surface of...

Q. Spherical glass particles (12 mm diameter and 2500 kg/m 3
density) and spherical metal particles (1.5 mm diameter and 7500
kg/m3) are falling in water (density= 1000 kg/m3) .
(1) Calculate the terminal falling velocities of glass and metal
particles in water for a constant friction factor of 0.22.
(2) At what water velocity will fluidized beds of glass
particles and metal particles have the same bed densities?

Consider a well-mixed tank filled with 200 L of liquid
containing a chemical A at the concentration of 4 mol/L which
decomposes following a first order kinetics RA=k.CA with a rate
constant of k=0.05 min-1 . At t=0 an outlet stream starts to leave
the tank with the flow rate of 5 L/min. After the liquid level
falls to the half of the initial level, an inlet stream with CA=4
mol/L starts entering the tank at a flow rate of...
