1.Using the DeHoff method, compute the change in internal energy when 12 liters of argon gas at 273 K and 1 atm is compressed to 6 liters with the final pressure equals to 10 atm. Assume argon behaves ideally and CV = 3/2·R. Show details of the entire derivation.
2.Estimate the buoyant force on 10'x10' by 2' deep balsa (SG=0.2) raft with you in it. How deep is it in the water? Be sure to draw well leveled schematic of the system.
Each month the speedy dry Cleaning company buys 1 barrel (0.160 m^3)of dry cleaning fluid . Ninety percent of the fluid is lost to the atmosphere and 10 percent remains as residue to be disposed of
Statistics indicate that the world population since World War II has been growing at the rate of 1.9% per year. Further, United Nations records indicate that the world population in 1975 was (approximately) 4 billion.
What is the vapor pressure of carbon dioxide in the bottle before it is opened (i.e., when it is at equilibrium) assuming no other ions are present besides those related to CO2 and water
Calculate the relative velocity of a solute front that is flowing through an aquifer. The organic carbon partitioning coefficient (Koc) is 6 mL/g and the friction of organic carbon in the soil is 2%.
If D1 = 60 cm, D2, = 40 cm, D3 = 54 cm, L1 = 400 m, L2 = 450 m, and L3 = 750 m. Assume f = 0.0125 (3 riveted steel pipes). Determine the total flow if the system head loss is 60 m.
given: Vf=Vi + a t and Sf=Si + Vi t + 1/2 a t a= 27 ft/sec^2 accelerates from 10 mph to 93 mph in 4.5 seconds designers decided to modify the rise to become the tallest roller coaster in the world, find final velocity in mph if the drop height is ..
A surveyor measures an angle with two instruments; call them A and B. Both instruments produced unbiased measurements, but the standard deviation of measurements made with instrument A is twice that of B.
During a particular 30-day period, the streamflow flowing into a reservoir averaged 5.0 m3/s. Water supply withdrawals from the reservoir averaged 136 mgd. The only other outflow from the reservoir was 9.4 cm of evaporation from the water surface.
Determine the minimum size of the pad footing 2 metres wide for a steel column if a factor of safety of 2.0 is recommended (include an estimate of self weight of the footing in your calculations). The total load of the column is 447.644kN
Radon from well water may pose a radiological health hazard. One treatment technique is simply to hod the water in storage, allowing the radon to decay. The decay rate is first order:
Two 52 kN loads are maintained 2.5 m apart as they are moved slowly across beam AB. Write a computer program to calculate the deflection at the midpoint C of the beam for values of x from 0 to 9 m, using .5 m increments.
What is the difference in the density and specific weight of air if pressure increases from 1 to 50 atmospheres if temperature is kept at 4 degrees Celsius
