The actual temperature of a parcel of air is 300 K. The total pressure is 100 kPa and its vapor pressure is 2 kPa. Its virtual temperature is (nearest integer) 302 K 300 K 298 K 305 K

Air is compress from 100 kPa and 50°C to 2000 kPa and 500°C. Assuming constant specific heats, determine the change in the specific entropy of air.Group of answer choices-0.0478 kJ/kg.K1.767 kJ/kg.K0.0478 kJ/kg.K-1.767 kJ/kg.K

At 2 km above the atmosphere, the temperature for a parcel of dry air is 10 ooC and pressure is 800 hPa. What is the potential temperature of this air parcel? Cpp of air 1.005 kJ/kgK and ideal gas constant of air is 0.287 kJ/kgK 290 K 296 K 302 K 308 k

The Relative Humidity of a parcel of air is 0.5. The saturation vapor pressure is 2 KPa. The partial pressure of dry air is 100 KPa. How many grams of vapour is present per kg of dry air? 3.11 gm 6.22 gm 12.44 gm 62.2 gm

A saturated parcel of air is cooled from a temperature where saturation vapor pressure is 3 kPa to a temperature where the saturation pressure is 1 kPa. The total pressure is 100 kPa throughout. If the air parcel contains 1 kg of dry air, how much water vapour (in grams) will condense out of this air during the process? (Answer to nearest integer) 6 gm 9 gm 13 gm 26 gm

If the atmospheric pressure is 101.3 kPa and the temperature is 25°C25°C, what is the density of air? (Use the ideal gas law)
