Answer:
water temperature change = 0.696° F
Explanation:
In this question we will consider the steady flow energy equation at the Top and at the bottom of the water falls and also assume the flow is Adiabatic
we will apply the relation below to Estimate the water temperature change caused by the drop
------ ( 1 )
where : Cp = 25100 ft. Ibf / slug °F
Δ z = 543 ft
g = 32.2 ft/s^2
Input the given values into equation 1 and make t subject of the relation
t ( temp change ) = 
= 0.696° F
Sunlit zone is depth of water exposed to sunlight, trenches is a long narrow ditch.
the capital of iran is Tehran or Teheran.
they can not go down into the Earth at all. Due to technology, we would need better technological advances.
Oil still plays an important role in the global economy despite the continued efforts to reduce its use and to find alternative green energy sources. In the early days, finding oil during a drill was considered somewhat of a nuisance as the intended treasures were normally water or salt. It wasn't until 1847 that the first commercial oil well was drilled in the Absheron Peninsula, Azerbaijan.1 The U.S. petroleum industry was born 12 years later, in 1859, with intentional drilling near Titusville, Pennsylvania. (Drilling in the United States began in the early 1800s, but they were drilling for brine so any oil discovery was accidental.)2
