Explanation:
Bernoulli equation for the flow between bottom of the tank and pipe exit point is as follows.
     =
 = 
     ![\frac{(100 \times 144)}{62.43} + 0 + h[tex] = [tex]\frac{(50 \times 144)}{(62.43)} + \frac{(70)^{2}}{2(32.2)} + 0 + 40 + 60](https://tex.z-dn.net/?f=%5Cfrac%7B%28100%20%5Ctimes%20144%29%7D%7B62.43%7D%20%2B%200%20%2B%20h%5Btex%5D%20%3D%20%5Btex%5D%5Cfrac%7B%2850%20%5Ctimes%20144%29%7D%7B%2862.43%29%7D%20%2B%20%5Cfrac%7B%2870%29%5E%7B2%7D%7D%7B2%2832.2%29%7D%20%2B%200%20%2B%2040%20%2B%2060)
                           h = 
                             = 60.76 ft
Hence, formula to calculate theoretical power produced by the turbine is as follows.
                                  P = mgh
                                      = 
                                      = 6076 lb.ft/s
                                      = 11.047 hp
Efficiency of the turbine will be as follows.
                  =
 =  × 100%
 × 100%
                                 =  
                       
                                 = 52.684%
Thus, we can conclude that the efficiency of the turbine is 52.684%.

Answer:
7 and 11
Explanation:
The amount of sand on the beaches can be found using this formula:
volume (m3) = length (m) × width (m) × depth (m)
(6 × 108 m) × 60 m × 20 m = 7 × 1011 m3
Therefore, there would be a total of 7 × 1011 cubic meters of sand on the beaches.
 
        
             
        
        
        
The answer is covalent bonding. Molecular compounds are made of 2 or more nonmetals, and are therefore covalent. That is why another name for "molecular compound" is "covalent compound".
Answer: (1) covalent bonding
