1. Spy balloon is to be constructed of a material with a mass of 0.5kg. it will be filled with helium and must be able to carry and instrument payload of 50kg at an altitude of 1000m where the density of the air is 1.16 kg/m^3. what mass of helium will be required.
2. If the temperature of gas (measured in K) is doubled
a-the rms speed of the molecules doubles
b-the rms speed increases bh a factor of 2
c-the average kinetic energy quadruples
d-the average kinetic energy increases by a factor of 2
3. A 1-liter container of nitrogen gas (N2) at a temperature of 23c is intially at a pressure of 1.25 atm. because of a slow leak the pressure falls to 1.15 atm 1 hour later what is the leak rate in molecules/second?
4. How much energy is required to melt a 500cm^3 block of lead intitially at a temperature of 20c?
Elemental iodine (I2) is a solid at room temperature. What is the major attractive force that exists among different I2 molecules in the solid?
Burning the coke deposited on the catalyst particles generates all the heat necessary for catalytic cracking. Therefore, the coke burning rate is a critical parameter to control the rate of cracking. The composition of dry flue gas from the regenerat..
The line is commercial steel pipe, 25 mm internal diameter, length 120 m. The properties of the fluid are: viscosity 0.99 mNm-2 s, density 998 kg/m3. Calculate the total pressure drop due to friction when the flow rate is 3500 kg/h
Acetone of at least 95 mol% purity is wanted, and the aqueous effluent must not contain more than 1 mol% acetone. The feed will be a saturated liquid. Estimate the number of ideal stages required.
A spherical ball of benzoic acid (diameter = 1.5 cm) is submerged in a pool of still water. The solubility and diffusivity of benzoic acid in water are 0.03 kmol/m3 and 1.25 x 10-9 m2/srespectively.
The addition of an oxidizing agent such as chlorine water to a clear solution of an unknown compound results in the appearance of a brown color. When this solution is shaken with the organic solvent, methylene dichloride, the organic solvent layer..
This is a fluid dynamics experiment involving the filling and emptying of tanks. The objectives of the experiment include: Determination of the discharge coefficient of the orifice and the equivalent length of a pipe mounted at the outlet of the two..
10g of steam at l00°C and a pressure of one atmosphere condensing into water at the same temperature and pressure. (The latent heat of vaporization of water is 22571 Jg^-1).
A black body of finite dimension at 1000K is inserted into an infinite medium at 300 K. Given Stefan Boltzman constant as 1.8*10-5 W/m2K4, the radiative heat transfer coefficient is ------
A loaded semi-truck consumes about 10 US gallons of diesel per hour (assuming an average speed of 60 mph) and is driven about 16 hours per day, every day of the year. The density of diesel id 0.85 kg/liter. If 1 barrel of crude oil produces 10..
Devise a control system for this reactor, and draw up a preliminary piping and instrument diagram. The following points need to be considered:
The hydrogen produced was successfully vented and no chemical explosion occurred. If 1.00 103 kg of Zr reacts, what mass of H2 is produced? What volume of H2 at 1.0 atm and 1000.°C is produced?
