An Electrostatic Precipitator (ESP) have 6 collector plates whose dimension are 20 x 30 m each. It is used to treat 160 m3/s of gas with a flow velocity of 0.102 m/s at an efficiency of η. if the flow rate of gas increase to 380 m3/s at a velocity of 0.2 m/s then calculate the number of collector plates required to maintain the same efficiency.
Enter numerical value using the virtual keypad. Round off where necessary.
