Solution:

The mean indoor airborne Chloroform (CHCl₃) concentration in a room was determined to be 0.4 μg/m³.

Use the following data: T = 293 K, P = 1 atmosphere, R = 82.05 × 10^-6 atm-m³/mol-K.

Atomic weights: C = 12, H = 1, Cl = 35.5.

1.00 ppbv

0.20 ppbv

0.10 ppbv

0.08 ppbv

Solution:

Consider the following statements.
(i) CO possesses about 200 times affinity for blood haemoglobin than oxygen.
(ii) Major source of corrosion is Taj Mahal is SO2.
(iii) The most prominent air pollutant which causes severe damage to the plants is bromine.
(iv) When the ELR is more than ALR, it is known as stable environment.
Of these statements

(i) is only correct

(i) and (ii) are correct

(i) (ii) and (iv) are correct

None of them are correct.

Solution:

A baghouse filter has to treat 12 m³/s of waste gas continuously. The baghouse is to be divided into 5 sections of equal cloth area such that one section can be shut down for cleaning and/ or repairing, while the other 4 sections continue to operate. An air-to-cloth ratio of 6.0 m³/min-m² cloth will provide sufficient treatment to the gas. The individual bags are of 32 cm in diameter and 5 m in length. The total number of bags (in integer) required in the baghouse is_______.
