Compare the number of bags required for a pulse jet baghouse versus a reverse air baghouse servicing a foundry gas flow of 75m3/ s. Assume a gas-to-cloth ratio of 0.5 (m3/s)/m2, and bag dimensions of 0.3m diameter by 2.5m in length for the pulse jet unit and a gas-to-cloth ratio of 0.1 (m3/s)/m2, and bag dimensions of 0.6m diameter by 7.0m in length for the reverse air bag house. With this information, calculate the appropriate number of rows and columns of bags for each baghouse type.
