1. The instantaneous liberation rate of methane
in a room being advanced by a continuous
miner varies from 0.05 m3/s to 0.28 m3/s.
Calculate the quantity of fresh air containing no
methane that must be delivered to the working
place to maintain continuously the methane
concentration at the face at less than 0.5%.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffb9c98b3-38f2-4db7-9971-9761d303c5e0%2F6f571aec-919b-41dd-acc4-66d351e24475%2F7fh1gq5_processed.jpeg&w=3840&q=75)
