Mine water flowing at 1.5 m3/s with 2 mg/l dissolved oxygen, joins riverwater flowing at 7 m3/s containing 6 mg/l dissolved oxygen. The saturated value of the dissolved oxygen in the mixture is given to be 9.3 mg/l. On the basis, the initial oxygen deficit of the mixture in mg/l is
Bottled water is drinking water (e.g., well water, distilled water, mineral water, or spring water) packaged in PET Bottle or Glass Water Bottles. Bottled water is comprehensively regulated by the U.S. Food and Drug Administration (FDA) as a packaged food product. By law, the FDA regulations for bottled water must be at least as stringent as the Environmental Protection Agency standards for tap water. What inference can be drawn from the above passage?
Suppose saturated polar air has an air temperature and dew point of -10o C, and unsaturated desert air has an air temperature of 35o C and a dew point of 10o C. The desert air contains ______ water vapour and has a ________ relative humidity than the polar air.
The Henry’s law constant for O2 in water at 25°C is 1.27×10−3M/atm and the mole fraction of O2 in the atmosphere is 0.21. Calculate the solubility of O2 in water at 25°C at an atmospheric pressure of 1.00 atm. Strategy: ▪ Use Dalton’s law of partial pressures to calculate the partial pressure of oxygen. ▪ Use Henry’s law to calculate the solubility, expressed as the concentration of dissolved gas.
Statement I: The condenser in a steam power plant is always filled with a mixture of water, steam and air. Statement II: Slightly wet steam enters the condenser wherein the pressure is below the atmospheric conditions, causing some leakage of air through the glands and also the release of some air dissolved in the boiler feed water.
In air-conditioning systems, air may be cooled and dehumidified by 1. Spraying chilled water to air in the form of fine mist. 2. Circulating chilled water or brine in a tube placed across the air flow 3. Placing the evaporator coil across the air flow. Which of the above statements are correct?
A three-star medicine is prepared by mixing two type of fluids (A & B) in ratio of 1 : 4. Fluid A is prepared by mixing two type of water, water M and water N in ratio of 4 : 5. Fluid B is prepared by mixing two type of water, water X and water N in ratio of 3 : 7. The final mixture is prepared by 675 units of three-star medicine with water Y. If the concentration of the water N in the final mixture is 60%, then how much water Y had been added to three-star medicine?
In MPFI-Air Induction System, the air cleaner, the air flow meter, the throttle body and the air valve supply a proper amount of air to the air intake chamber and intake manifold.
At equilibrium the concentration of water in vapour phase (C*) in kg/m3 of air space and the amount of water (m) adsorbed per kg of dry silica gel are related by, C* = 0.0667 m. To maintain dry conditions in a room of air space 100 m3 containing 2.2 kg of water vapour initially, 10 kg of dry silica gel is kept in the room. The fraction of initial water remaining in the air space after a long time (during which the temperature is maintained constant) is
