A channel of triangular cross section, which is 25 mlong
Chapter 7, Problem 7.131(choose chapter or problem)
A channel of triangular cross section, which is 25 mlong and 1 m deep, is used for the storage of water.The water and the surrounding air are each at a tem-perature of 25?C, and the relative humidity of the airis 50%.(a) If the air moves at a velocity of 5 m/s along thelength of the channel, what is the rate of water lossdue to evaporation from the surface?(b) Obtain an expression for the rate at which thewater depth would decrease with time due to evap-oration. For the above conditions, how long wouldit take for all the water to evaporate
