Design a cyclone that has a collection efficiency between 80% and 85% (use parcticle size distribution given below). you must assume a dpc of 4.2 microns,an inlet gas velocity of 25 m/s and a K of 15.The unit must handle 20,000 cfm of contaminated air (225 degrees F, 1 atm)with a pressure drop no greater than 9 inches of water.The gas viscosityis 0.058 kg/m per hour, the gas density is 0.89 kg/m3.Indicate the removal efficiency, the cyclone body diameter,the pressure drop for the design. Also determine the other physical dimensions of the cyclone; Height of inlet, width of inlet,diameter of gas exit,length of vortex finder,length of body,length of cone and the diameter of dust outlet.
Weather records for a certain region indicate that there is a tendency for two hot summers to occur in a row. From the statistics for the region, the following information has been es tahlished
A floor is to be supported on hardwood timber joists that are spaced at 0.5m centres and span 5.0m. The joists support flooring 20mm thick and an applied live load of 2kN/m2
A 110 f t long, 5 in in diameter (f = 0:033) connects two reservoir whose water surface elevations differ by 12 f t. Compute flow rate in pipe.
Determine the cycle time of the trucks, including load, haul, dump, and return. The haul and return times are given above. When calculating load time, round up the number of MINUTES to the nearest whole number.
Roller coasters are designed so that the riders will not experience more than a certain level of g-force during the ride. (The rider would experience B g's if hte normal force were Bmg where B is a numbe
the 3.5mg engine is suspended from a 500 kg spreader beam and hoisted by a crane which gives it an acceleration of 4m/s^2 when it has a velocity of 2m/s. determine the force in chains AC and AD during the lift.
If metal sorption to algae can be modeled by a Langmuir isotherm, determine the mass distribution (sorbed vs dissolved) of lead in the marsh.
what is the definition of critical state. explain at which stage a critical state may be approached in a drained triaxial text on a overconsolidated clay using stress path and strain-strain plot.
The acceleration of a particle is defined by the relationship a=-kx^-2 ft/s^2, where x is in feet and k is a constant. At x(0)=0.1ft, v(0)=0 and at x(1)=1ft, v(1)=10ft/s. Find the velocity at x=5ft.
A surface water sample has been evaporated until dry in a crucible dish. The dry (tare) weight of the crucible is 44.642gm. The weight of the residue plus the cruciible is 44.6484gm.
Pure water at 50 degrees Fahreneit stands in a glass tube of 0.04-in diameter at a height of 6.78 in. Compute the true static height.
There are three 18 mm diameter steel bolts that are attached to a plate. The plate can support up to a 110 KN load, and the ultimate shear stress is 360 MPa. Determine the factor of safety for the given design.
