Answer / murthy

dew point temp is temp at which the first dew will be
formed if compressed. air dew point is defined because of
dew formation due to C02 & water which forms dry ice ,not
because of air liquefication.air with dew point -40C means
it is temperature upto which there will be no dew formation
upto this temp if pressure is increased even upto critical
pressure

Answer / vaibhav v t

-40C dew point in air drying means air will be condensed
at -40 deg.c only.-40 C means good dry air.

Answer / ramana reddy

at -40c the air will become to liquified. above this temp.
air in vapor state.

Answer / samy

Air dew point is -40C because of decC and decF are meet in -40

Question 82 - (a) The Hyperion sewage plant in Los Angeles burns 8 million cubic feet of natural gas per day to generate power in United States of America. If 1 metre = 3.28084 feet, then how many cubic metres of such gas is burnt per hour? (b) A reservoir of natural gas produces 50 mole % methane and 50 mole % ethane. At zero degree Celsius and one atmosphere, the density of methane gas is 0.716 g / L and the density of ethane gas is 1.3562 mg / (cubic cm). The molar mass of methane is 16.04 g / mol and molar mass of ethane is 30.07 g / mol. (i) Find the mass % of methane and ethane in the natural gas. (ii) Find the average density of the natural gas mixture in the reservoir at zero degree Celsius and one atmosphere, by assuming that the gases are ideal where final volume of the gas mixture is the sum of volume of the individual gases at constant temperature and pressure. (iii) Find the average density of the natural gas mixture in the reservoir at zero degree Celsius and one atmosphere, by assuming that the final mass of the gas mixture is the sum of mass of the individual gases. Assume the gases are ideal where mole % = volume % at constant pressure and temperature.
