1.Derive an equation and solve for the volume V of a CSTR, operated isothermically for the second-order reaction 2R->P, where rR=-kC^2 R. Data are k=6.0 L/mol-s, CRin=0.005 mol/L, CRout=0.0005 mol/L, and Q=100 L/s.
2.A tank contains 3,500 cubic meters of water and has a total sodium chloride (NaCl) concentration of 1,520 mg/L. Clean water (it has no sodium chloride) is then added to fill the tank up to a final volume of 4,000 cubic meters. The final sodium chloride concentration in the tank is [x1]mg/L. Report answer to the nearest 10 mg/L.
Determine the mass of the earth knowing that the mean radius of the moons orbit about the earth is 238.910mi and that the moon requires 27.32 days to complete one full revolution about the earth
If the length of the river connection between the two lakes is equal to 3km and the velocity in the river is equal to 0.4 m/s, determine the concentration of UBOD in the effluent from the second lake.
In part (a) of this question we are asked to calculate τmax. In order to do this we separate the cross section at the neutral axis and take the entire upper half (as shown in the cramster solution).
For the free-falling patachutist with linear drag, assume a firstjumper is 70 kg and has a drag coefficient of of 12 kg/s. If a second jumper has a dragcoefficient of 15 kg/s and a mass of 75 kg, how long will it take him to reach the same velocity t..
A certain gas weighs 16.0 N/m3 at a certain temperature and pressure. What are the values of its density, specific volume, and specific gravity relative to air weighing 12.0 N/m3 ?
Draw the influence line for the tension in cable BC. Neglect the thickness of the beam, What is the maximum tension in the cable due to the 6-k loading
Helium (Hrom an intie) at a rate of 1.5 lbm/s is compressed inan adibatic compressor from an intial condition of 70 F, 14.7 Psiato final condtion of 1070 F, 147 Psia. Determine The power required to run his compressor
The frame ACD is hinged at A and D and is supported by a cable that passes through a ring at B and is attached to hooks at G and H. If the tension in the cable is 1125 N (thus 1125 N in section BG and 1125 N in section BH)
What is the expected boiling-point elevation of water for a solution that contains 271 g of sodium chloride dissolved in 1.0 kg of water?
A constant head permability test is performed on a soil that is 2 cm X 2 cm square and 2.5 cm long. The head difference applied during the test is 18 cm, and 5 cm^3 is collected over a time of 100 sec.
A car travels along a horizontal circular curved road that has aradius of 600 m. If the speed is uniformly increased at a rate of 2000 km/ h2 , determine the magnitude of the acceleration at the instant the speed of the car is 60 km/h.
Determine the drag force FD on a golf ball assuming it is a smooth sphere. (Assume the air is at 60 F and standard pressure.) Now determine the drag force on an actual golf ball assuming CD = 0.25. How do the two forces compare
