Condenser cooling water for a power plant is stored in a cooling pond that is ( 1000 mathrm{~m} ) long by ( 500 mathrm{~m} ) wide. However, because of evaporative losses, it is necessary to periodically add makeup water to the pond in order to maintain a suitable water level. Assuming isothermal conditions at ( 27^{circ} mathrm{C} ) for the water and the air, that the free stream air is dry and moving at a velocity of ( 2 mathrm{~m} / mathrm{s} ) in the direction of the ( 1000 mathrm{~m} ) pond length, and that the boundary layer on the water surface is everywhere turbulent, determine the amount of makeup water that should be added to the pond daily.

Condenser cooling water for a power plant is stored in a cooling pond that is 1000m long by 500m wide. However, because of evaporative losses, it is necessary to periodically add makeup water to the pond in order to maintain a suitable water level. Assuming isothermal conditions at 27C for the water and the air, that the free stream air is dry and moving at a velocity of 2m/s in the direction of the 1000m pond length, and that the boundary layer on the water surface is everywhere turbulent, determine the amount of makeup water that should be added to the pond daily.
