A channel of triangular cross section, which is 25 m long and 1 m deep, is used

Question:

A channel of triangular cross section, which is 25 m long and 1 m deep, is used for the storage of water.

Tt/2 z = 1 m

The water and the surrounding air are each at a temperature of 25°C, and the relative humidity of the air is 50%.

(a) If the air moves at a velocity of 5 m/s along the length of the channel, what is the rate of water loss due to evaporation from the surface?

(b) Obtain an expression for the rate at which the water depth would decrease with time due to evaporation. For the above conditions, how long would it take for all the water to evaporate?
