Steam economy is defined as the amount of evaporation per unit amount of steam used, while the capacity is the total evaporation obtained per hour. Use of multiple effect in evaporation
Consider the following statements and choose the correct answer:
1. Evaporation is a vital physiological process
2. Transpiration is restricted to living bodies only
3. Evaporation is as low loss of water molecules to the unsaturated atmosphere from the free exposed surface among living and non-living bodies
4. Transpiration is simply a loss of water molecules which do not involve any pressure
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?
Consider the following statements in connection with soil-water-crop relationship: 1. Water utilization by plants is mainly from capillary water. 2. The amount of irrigation water required to meet the evapotranspiration needs of the crop during its full growth duration is its consumptive irrigation requirement. 3. The depth of water required to bring the soil-moisture level of a given soil up to its field capacity is called hygroscopic water. 4. With continuous increase in quantity of water applied, the yield of most crops increases up to a certain limit and then is expected to be constant. Which of the above statements are correct?
