Determine the density specific impulse (Id) if the specific impulse is 315 s and the average density of the propellants is 840 kg/m3. Take the reference density to be the maximum density of water.
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?
Which of the following statements are correct about sea water. (A) The density of sea water depends upon temperature, pressure and salinity (B) Convergence of water has no effect on density (C) The thermal expansion of water varies with the increase and decrease of temperature (D) In the middle latitudes, due to an excess of precipitation the density is higher Choose the correct answer from the options given below:
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?
About 40 million people (over 75% are children) are affected by water borne diseases every year. Nearly six million children below 14 years of age suffer from fluorosis due to fluoride contamination in water. Arsenic is another dangerous contaminant in ground water, putting at risk more than 10 million people in the country. Bacteriological contamination, which leads to diarrhea, cholera, hepatitis etc., is at alert level in India. Contamination due to Iron, hardness and salinity in water are other major concern. Medical expenditure on water borne diseases is estimated to be Rs. 2400 crores annually in the country. The need for desalination and water purification is destined to grow in the coming years as the requirement for water increases. Bhabha Atomic Research Centre (BARC) has been engaged in R&D on desalination and water purification technologies for several years and has developed indigenous technologies which are available for know-how transfer to interested parties The given information, if accurate, most accurately supports which statement?
