- Assume that a certain type of cyclone has a particle cut diameter of 6 microns; (a) calculate the overall efficiency of this cyclone on the particles of Problem 4.4 and (b) calculate the overall efficiency of two of these cyclones placed in series.(b) Evaluate the support reactions forces of the loading diagram shown in Figure Q5(b) 80KN 20KN 5m 3m 2m RA RD Figure Q5(b)mass in a physics experiment, a metal bar is balanced on a fulcrum. A 5.0 kg. is placed on the bar, 45.0 cm from the fulcrum, and on the same side a 2.0 kq mass is placed an unmeasured distance away from the fulcrum. Another mass (12 kq) is placed on the other side of the fulcrum, 50.0 cm away. away How far fulcrum! is the 2.0 kg mass from the 45.0cm 50.0 cm 5.0kg 2.0kg 12 kg
- A small block slides at a speed von a horizontal surface. Knowing that h=04 m, determine the required speed of the block if it is to leave the cylindrical surface BCD when 0 = 35". The required speed of the block to leave the cylindrical surface is m/sA person has a mass of 45 kg is running with a velocity of 12.0 m/s. All of a sudden, the person plants their feet and stops abruptly in 3.75 m. This was some mighty agressive stoppage power! Your answer to part (a) may reflect that. a. What was the coefficient of friction between their shoes and the ground in order to do so? b. If it took place in 0.625 seconds how much power was expended by friction on the person?The effect of surface tension on the mass of a falling drop is studied. According to Raleigh for non-viscous flow the mass of a drop, ma, is a function of the surface tension, σ, the diameter of the droplet, d, the gravity, g, and the flow density, p. ma = f(d,g,p,σ) Find the relevant dimensionless numbers.
