The highest pressure gas of a mixture has partial pressure p, the partial pressure of other gases decreases by factor of 2n-1, the partial pressure of second gases decreases by a factor of 2, partial pressure of third gas increases by 4, and so on, if the total pressure of gas mixture is 31p/16, how many gases are present in the mixture?
In a newly developed innovative idea brought up by CSIR in India, gas turbine exhaust gas are being utilized to convert feedwater into steam. Certain data of the experiment are as follows: mass flow rate of exhaust gas = 40 kg/hr, enthalpy of exhaust gas at the time of their exit from gas turbine is 600 kJ/kg, steam turbine output as measured by brake dynamometer = 60 hp-sec, thermal efficiency of steam power plant is 0.25, efficiency of exhaust gas in converting feedwater into steam is taken as 50%. Find the enthalpy of exhaust gas remaining after they generate steam from feedwater?
Which of the following statements about partial pressure are correct? Statement 1: The partial pressure of each gas in a mixture is not proportional to its mole fraction.. Statement 2: The partial pressure of each gas is the product of the total pressure and the mole fraction of that gas.
In a compound steam engine, the first stage of expansion is carried out in a high pressure cylinder whereas the last expansion is completed in low pressure cylinder. The diameter of high pressure cylinder is _________ the low pressure cylinder.
Air at a density of 1.2 kg/m3 flows in a straight duct such that the velocity at the centre is 12.5 m/s. the method factor for the velocity profile is known to be 0.80. The air flow encounters a symmetric expansion such that the cross- sectional are of the duct becomes double. The static pressure value at the inlet and outlet of the expansion are 60 Pa and 90 Pa respectively. Neglecting friction the shock pressure loss on account of expansion in Pa is
India's first gas exchange, the Indian Gas Exchange (IGX), was launched as a wholly owned subsidiary of Indian Energy Exchange. Which of the following statements are correct? 1. It is a digital trading platform that will allow buyers and sellers to trade both in the spot market and in the forward market for imported natural gas. 2. It will allow trade across three hubs - Dahej and Hazira in Gujarat and Kakinada in Andhra Pradesh. 3. Imported Liquified Natural Gas (LNG) will be regassified and sold to buyers through the exchange, removing the requirement for buyers and sellers to find each other. 4. Only inter-governmental trade in domestically produced natural gas is allowed at the gas exchange. Select the correct answer using the code given below:
What is the molal humidity of a gas with pressure of gas vapor 10 mm Hg and pressure of vapor free gas 20 mm Hg?
Dalton’s law of partial pressure states that the total pressure exerted by a mixture of gas and vapour is the sum of partial pressure of the gas and partial pressure of the vapour at the common temperature.
Under standard temperature (T) and pressure (P) conditions, 128 g of an ideal gas molecule A occupies a volume of 1 L. The gas molecule A obeys the relationship RT = 0.25 PV. R and V are universal gas constant and ideal gas volume, respectively. The molecule A is
A sample of ideal gas with initial pressure p and volume V is taken through an isothermal expansion proceed during which the change in entropy is found to be ΔS. The universal gas constant is R. Then the work done by the gas is given by
