LPG gas cylinder price with effect from October 1: State-run oil marketing companies such as Indian Oil Corp (IOC) raised the retail prices of commercial LPG (sold in 19 kg cylinders) with effect from October 1, 2023. However, the prices of domestic LPG (14.2 kg cylinders) were left unchanged at existing levels.
Therefore the tonnes CO2 equivalent of 10kg of hydrofluorocarbon ( HFC) 404a is calculated as follows: Mass (in metric tonnes) of F gas multiplied by GWP of F gas. = (10/1,000) * 3,922. = 39.2
Hydrogen weighs 0.000082 gram per cubic centimeter or 0.082 kilogram per cubic meter, i.e. density of hydrogen is equal to 0.082 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure. In Imperial or US customary measurement system, the density is equal to 0.0051 pound per cubic foot [lb/ft³], or 0.0000474 ounce per cubic inch [oz
where r B is the balloon radius. Using the value of V B in eq. 3, we find that the radius of the balloon is. r B = 93 m. 5. If hydrogen is used instead of helium, then we set m H2 = 1.67 x 10 -27 kg in the ideal gas law, and repeat the above procedure to find. G = 1.16 x 10 -7 kg/m 3. 2a. V B = 3.03 x 10 6 m 3.
