Answer / manikandan

In a cooling tower the hot water is sprayed into small
droplets and allowed to flow from the top to the bottom at
the same time due to the contour flow (in natural draft
cooling towers) air is flowing from bottom to top and there
will be a slight pressure difference inside the cooling
tower with regarding to the atm pressure. The air
temperature will be less than the water temperature and the
hot water is cooled by loosing its sensible heat and some
portion of the water is evaporated.

Answer / k.l.subrahmanyam (nb ventures)

due to counter flow of water & air heat exchange will be done in this process vapors are generated

Answer / vamsee krishna

i think when the water is flowing through the cooling tower
the cooling media is flown in the opposite direction and the
heat transfer takes place bet these two so then the water
takes the heat of the hot air so that the vapor is formed

Answer / rakeshkumar

in cooling tower the water is made into a very small drops,
and it is made fall from top to bottom of d tower,so tat it
is directly contact with air and heat exchangeis taking place

Answer / manoj kumar

it is right the water is flow counter, but the cooling is
due to the heat and mass transfer

Answer / ayushya shroti

water after it leaves the cooling tower is pumped to industrial applications using heat exchange, condensers, air compressor jackets, or process reactors. In this cycle, the water returning to the cooling tower water has absorbed excess heat from the manufacturing process which is then dissipated by spraying the water through a water cooling tower where partial evaporation takes place. The cooling tower exposes the heated water to air, causing a percentage (~1-3%) of the water to evaporate, which removes a substantial amount of heat in the process. The water that doesn’t evaporate is cooled and then reused.

Answer / ritesh pokarna

In cooling tower ,the tubes are bent in horizontal manner
because of these .in this tube the steam is flowing ,as
water is falling to these tube the vapour inside the tube
are evaporated
