A rigid tank is divided into two compartments by a partition. One compartment contains 3 kmol of N2 at 600 kPa and the other compartment contains 7 kmol of CO2 at 200 kPa. Now the partition is removed, and the two gases form a homogeneous mixture at 300 kPa. The partial pressure of N2 in the mixture is
(a) 75 kPa
(b) 90 kPa
(c) 150 kPa
(d ) 175 kPa
(e) 225 kPa
A thin-walled circular tube has an average diameter of 100 mm and a wall thickness of 4 mm. It is subject to torque of 4 kNm and a compressive axial force of 40 kN.
a sewage treatment works stw with 4 single-stage trickling filters has become organically overloaded due to the
Assuming a linear speed-density relationship, the mean free speed is observed to be 60 mph near zero density, and the corresponding jam density is 140 veh/mi.
Given the data below for two alternatives, find the better alternative, if MARR is 8%. alt A |alt B Initial cost $10,000 |$15,000 maintenance cost/ year $1,000 |$500
Compare the total reactor volume required for 90% removal of a substance that decays according to first-order kinetics with a rate constant of 0.05 day -1 in a CM system that contains a single reactor against a system that contains three CM reacto..
What are the important findings in Austin Road Co. v. OSHRC and Builders Steel Co. v. Marshall? Your response should be approximately 200 - 300 words and include a reference citation for your response.
Calculate the R-value for the wall assembly. This calculation should be done by hand, on engineering paper, and handed in during class (or scanned and submitted online).
The cross-sectional area of the sample was 60 cm2 and its length was 150 mm. For 80 cm3/min steady-state flow rate, a total head difference of 8 cm was measured across two points separated by 10 cm along the axis of the sample.
Higher water level inside the eye, combined with wind results in a "storm surge". Calculate the force on the levee gates form storm surge 20 feet above level of the lake traveling at about 25 ft/sec.
An activated sludge system operates at a flow rate (Q) of 400 m3/day with an incoming BOD (So) of 300 mg/L. Throughout pilot plant work, the kinetic constants for this system are determined to be Y = 0.5 kg SS/kg
Determine the maximum hoop stresses on the inside fibers of a rifle barrel which is 3 feet long with an O.D. = 3.0" and an I.D. = 1.0". The internal pressure = 10,000 psi. Use the F.E. reference manual for determining these stresses.
the wastwater has a BOD5 of 1200 mg\liter that must be reduced to 200 mg\liter.if the mean cell residence time 5 days and suspended solids concentration of 5000 mg\liter and Y 0.7 kg\kg and kd 0.03 \day determine sludge recycle ratio R
