engineering recuitment GATE CE 2023-24 Test Series Environmental Engineering Air and Noise Pollution
An electric precipitator (ESP) installed across a polluted air supply of 180 m3/second delivered the removal efficiency of 97 percent, if the collector area of 6000 m2 was installed. Calculate the net increase in efficiency percentage (up to two decimal places) achieved if the same polluted air is dealt with the electric precipitator with a collector plate area of 6500 m2.
Enter numerical value using the virtual keypad. Round off where necessary.
