D、sphygmomanometer
A、pressure does not fluctuate rapidly B、pressure remains steady and unchanged C、brine density does not exceed 1~5 D、brine density is too low
A、Gravity siphon effect B、Higher vacuum in the second-stage C、Difference in brine density between first and second stages D、lower pressure in first-stage
A、in an area of high density the water's surface is lower than in an area of low density B、surface water flows from an area of high density to one of low density C、the lesser the density gradient the freer the water is to move D、it is the density differences that cause the currents to stay in the troughs
A、high density will be on the left in the Northern Hemisphere B、high density will be on the right in the Southern Hemisphere C、low density will be on the left in the Northern Hemisphere D、low density will be on the left in the Southern Hemisphere
A、increases brine density B、increases distillate salinity C、reduces metal corrosion D、reduces heat transfer
A、A.less internal corrosion because of lower brine density B、B.higher temperature evaporation for lower salinity of the distillate produced C、C.less scale formation in a flash evaporator D、D.less feed-water required for a flash evaporator
A、High conductivity of the distillate indicates distillate salinity is excessive B、Increasing the absolute pressure of the shell will increase the distillers capacity C、Mesh separators are used in evaporators to filter the distillate D、Reducing the brine density will reduce the heat lost overboard
A、Any time the vessel moves from water of one density into waters of a different density B、Prior to getting underway when the vessel is floating in fresh or brackish water C、Only when the vessel moves from fresh water into salt water D、The density of the water is not required to be logged in the unofficial logbook
A、lowering brine discharge density B、decreasing the absolute pressure of each stage C、increasing the saltwater feed heater temperature D、increasing the pressure at the spray pipe
