An industrial off gas steam must be treated for both particulates and SOx. The gas is at 1500 degrees F and 1.5 atm of pressure containing 80 mg/cubis meter of particulates and 25 mg/cubic meter of SOx. A two unit system is bring considered consisting of a cyclone followed by a venturi scrubber. The cyclone would remove 5% of the SOx (see below for particulates)with a pressure drop of 0.2 atm and no change in temperature.The scrubber would remove SOx with 95% removal efficiency (see below for degrees F) accompanied by a pressure drop of 0.3 atm and a temperature drop of 1000 degree F.The standard gas flow rate is 2000 scfm.Determine the emmisiion rate (kg/minute) for both particulates and SOx as well as the actual gas flow rate (acfm) emittted.Also determine the actual concentration (mg/cubic meter) for both pollutants for their emissions.
PARTICLE SIZE=0-5,5-10 AND >10PARTICULATE % BY WEIGHT=5,20 AND 75REMOVAL EFFICIENCY OF CYCLONE(%)=40,80 AND 92REMOVAL EFFICIENCY OF SCRUBBER (%)=95,98 AND 99.
A large rock became visible to a driver at a distance of 175 ft. Assuming a perception-reaction time of 0.8s, an initial speed of 42 mph, a coefficient of friction equal to 0.5, and a level roadway, calculate the speed at impact.
The dry weight of a core is 28.20 gm. When saturated with a brine having a density of 1.15 gm/cc, the weight increases to 31.50 gm. Calculate the apparent porosities if the matrix is 1) quartz or 2) calcite.
A reservoir discharge into a 60-inch concrete pipe (rough surface) that discharges freely. what is the pressure in the pipe at point A consider friction, but neglect minor losses.
A simply supported steel 'I beam' is made of three 1"*8" plates with a mass of 898.4 lbmass each as shown in I beam form. Steel has a modulus of elasticity of 30*10^6 psi. The beam is allowed to deflect 1.05 inch.
The cable is taut and prevents motion of point B in the x-z plane (i.e. acts as a pin for y-axis buckling), but offers no restraint to motion in the y-z plane (i.e. is unsupported for x-axis buckling).
A tank containing acetone at 20 oC has a drain pipe connected vertically at the bottom. The pipe is made of galvanized iron, 0.5 in NPS Schedule 40 with length L= 2m. The acetone depth in the tank is H= 5 m.
A ladder of mass 20 lbs. is leaned at an angle of 62 degrees against a smooth frictionless wall. What is the magnitude of the reaction (in lb-wt) where the ladder touches the wall?
Force F with magnitude indicated acts at point o. determine the magnitudes of the components Faa and Fbb along directions a-a and b-b so that F=Faa+Fbb
Determine the magnitude of reaction at point A (in kips) of a 20' beam with 5kips at 4' of the beam and 2kips at 9' of the beam at 350lbs./ft.
Two passenger cars are traveling at 65 MPH on a highway moving in the same direction in the same lane. The cars are separated by 25 feet for every 10 MPH of their speed. The coefficient of friction (skidding resistance) between the tires and the r..
A lunar module weights 1500 kg on earth where g = 9.75 mps2. On the surface of the moon where g = 1.70 mps2, what will be the force in Newtons required to accelerate the module at 10 mps2?
Assuming that the average stack gas velocity is 10.0m/s and the stack is circular with a 3.0 meter diameter, calculate the mass emissions rate of NO2 in kg/day.
