A cyclone has a body diameter of 1.0 meter. For air flow rate at 150 m³/min at 70°C and 1 atm, containing particles with a density of 1600 kg/m³ and a size distribution as given below, calculate the overall collection efficiency for a conventional cyclone type 3 given by Lapple. Taking the value of K as 15, calculate the cyclone pressure drop in kPa and the fluid power (kW) required to operate the cyclone. (viscosity of air at 70°C and 1 atm is 0.02 CP) TABLE 1: Size distribution of the particulates Particle Size Range, μm Mass % in Size Range 0-2 1 2-4 9 4-6 10 6-10 30 10 18 30 18-30 14 30-50 5 50-100 1 If the percentage of the particle size distribution has changed into the values as given in Table 2. Determine the new efficiency of the cyclone. Determine the different in cost of operating the cyclone by using tariff of RM0.25/kW.hr TABLE 2: Size distribution of the particulates Particle Size Range, μm Mass % in Size Range 0-2 30 2-4 30 4-6 14 6-10 5 10-18 10 18-30 9 30-50 1 50-100 1
