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.(SHOW ALL WORK)size range(um) Mass percent in size range0-2 42-6 176-12 1812-20 1920-40 2040-80 18>80 4
determine the maximum wind load that the cavity wall , bothe wythes are fully grouted but unreinforced ,and type S mortar portland cement is used . prism strength is equal to 2666psi for the concrete block wythe and 5333 psi for the brick wythe.
The double collar B is pin-connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r= 1.5(2-cos)
A steady-flow compressor is used to compress helium from 15 psia and 70oF at the inlet to 200 psia and 600oF at the outlet. The outlet area and velocity are 0.01 ft2 and 10 ft/s
Explain CBR method of pavement design with one example.
The 2 Mg car is being towed by a winch. If the winch exerts a force of T=105s on the cable, where 14m is the displacement of the car in meters, determine the speed of the car when s , starting from rest. Neglect rolling resistance of the car.
A ladder is supported by a horizontal floor and a vertical wall. Is 15 feet long and weighs 50 lbs, with the weight concentrated at its midlength. The ladder supports a person weighing 180 lbs.
The Record-a-Song company has contracted with a rising star to record eight songs. The sizes in MB of the different songs are 8, 3, 5, 5, 9, 6, 7, and 12, respectively. Record-a-Song uses two CDs for recording. Each CD has a capacity of 30 MB.
