Answer:
Time needed to empty the pool is 401.35 seconds.
Explanation:
The exit velocity of the water from the orifice is obtained from the Torricelli's law as
where
'h' is the head under which the flow of water occurs
Thus the theoretical discharge through the orifice equals
Now we know that
Thus using this relation we obtain
Now we know by definition of discharge
Using the above relations we obtain
The limits are put that at time t = 0 height in pool = 1.5 m and at time 't' the height in pool = 0
Solving for 't' we get
Answer:
Mass of cement used is 62.5 lb
Mass of gravel used is 225 lb
Explanation:
The ratio given here is cement to sand to gravel = 1 : 2.4 : 3.6
So, for 150 lb of sand
C : S : G = 1 : 2.4 : 3.6
Mass of cement used is 62.5 lb
Mass of gravel used is 225 lb
Answer:
Detailed solution is attached below in three simple steps the problem is solved.
