1. CO2 at 2200 lbf/in.2 is injected into the top of a 3-mi-deep well in connection with an enhanced oil recovery process. The fluid column standing in the well is at a uniform temperature of 100 F. What is the pressure at the bottom of the well, assuming ideal gas behavior?
2. Calculate the equilibrium constant for the reaction O2 ? 2O at temperatures of 537 R and 10 800 R.
3. Consider the dissociation of oxygen, O2 ⇔ 2O, starting with 1 lbmol oxygen at 77 F and heating it at constant pressure, 1 atm. At what temperature will we reach a concentration of monatomic oxygen of 10%?
If the 50 kg crate starts from rest and travels a distance of 6m up the plane in 4s, determine the magnitude of force P acting on the crate. The coefficient of Kinetic friction between the crate and the ground is 0.25
A 30 g bullet is fired with a horizontal velocity of 450 m/s through 3-kg block B and becomes embedded in carrier C which has a mass of 30 kg. After the impact, block B slides 0.3m on C before coming to rest relative to the carrier.
A 12 m-long and 800 mm-diameter drilled pier is constructed in a clayey soil with a1.5 m-diameter bell at the base. The top 7 m of the clay has an average Cu of 40 Kpa and the clay underneath has a Cu of 90 Kpa
you are designing a highway to AASHTO guidelines on rolling terrain where the design speed will be 65 mi/hr. At one section, a +1.25% grade and a -2.25% grade must be connected with and equal tangent vertical curve.
A 12-in well is drilled through a confined aquifer of average thickness 80 ft. Two observation wells located 50 and 120 ft away register a difference in drawdown of 10 ft. The steady-state pumping rate is 1000 gpm
A completely reversible air conditioner provides 21,000Btu/h of cooling for a space maintained at 81degF while rejecting heat to the environmental air at 91degF.
The space truss shown is supported by a ball-and-socket joint at D and by short links at A and C. Determine the support reactions and the force in each member of the space truss.
The position of a particle P moving in the horizental plane is described by r(t)= (5t^2 i +2te^0.1t j) m. Find the magnitude of the particle's position, velocity, and acceleration at time t=2 sec.
An airplane A takes off with a constant speed equal to vo=200 km/h. The path of the airplane is described by the equation y=kx^2, where k=6 x 10^-4 m^-1. Provide the expression for the velocity and acceleration of the airplane when x=390m. Express th..
A firm is considering moving its manufacturing plant from Chicago to a new location. The industrial engineering department was asked to identify the various alternatives together with the costs to relocate the plant, and the benefits. The engineers e..
Find the correction for the calibration of the measuring tape using its formula. During the calibration of the measuring tape on comparator of 100.000m the length of the tape turned out to be of 99.993m
Pressure loss in the suction pipe work is directly proportional to water veloicty in the pipe work squared, which is inversely proportional to suction pipe work diameter squared.
